Yes.
No.
No, at least temporarily.  Regardless, you may or may not be required to abstain from partaking the sacrament.  Your bishop/branch president will determine what is appropriate to your situation.
No, not if all of this was happening during that time.
No, the Lord will validate the baptism regardless of and in spite of your worthiness as a proxy.
Yes.
No, your ordinations are still valid.  They will become fully validated between you and the Lord upon your sincere and completed repentance.
Most likely you would be commended for your sincere desire to repent, overcome, and draw closer to the Lord.  You should expect to leave the meeting with him at peace and uplifted by the Spirit of the Lord.  You can expect the joy of knowing you are fulfilling the path of repentance the Lord has prescribed.  You might possibly be given a time frame to abstain from blessing, passing, or partaking of the sacrament.  The time frames may be different, such as don't partake for 1 month, don't pass or bless for 2 months; they might also be the same, the bishop will use the spirit to determine what is best.
Missionaries who falter with an act of masturbation, for example, are generally required to continue partaking the sacrament no matter what because the leadership of the Church have determined that it is prudent in the eyes of the Lord to not allow the members or investigators to question their worthiness.  While it is unlikely, given you are the only priest, there's always a very tiny chance that a similar inspiration could come to your bishop/branch president.
Over time you would become fully clean and be ready to serve a mission.  I would expect an absolute maximum length of 1 year for your repentance process, but given the specifics you have shared, if I were your bishop, I would say between 3 and 6 months would be more than enough to determine you have sincerely repented, and to walk with you through the repentance process.  (Disclaimer: I have never been a bishop or branch president)  In the MTC I learned that an Elder who confesses the sin of sexual intercourse while in the MTC is not sent home if his repentance has been and is sincere, so long as the transgression is more than 3 years in the past.  (No, I did not commit such a sin myself, however, it came up in an interesting discussion with my MTC branch president).
You will also very likely need to meet with the Stake President.  Sexual intercourse outside of marriage is a serious sin, and should not never be considered lightly.  Don't ever do it again, this is God's power being used improperly!
There would be no reason to not allow you to attend seminary.  In fact, your bishop would be well pleased with your desire to attend.  It is further evidence of your sincerity.
The bishop would not tell anyone (unless he felt it necessary to include your parents which is entirely reasonable), however, your parents might ask you on their own.  People will try and make guesses and might look at you funny.  That is the result of their own wickedness, pride, and improper judgement.  Regardless, I can assure you no one will ever know about your homosexuality unless you choose to disclose it, or unless your Church leaders act improperly (highly unlikely in a case like yours).  You have no cause to be ashamed for your repentance, only for your sins of the past.  Once your repentance is complete, you may consider it as if you had never committed those acts, for this is how the Lord sees it.  You will be clean!  
You will absolutely be able to go.  It is not even close to being too late.  I would expect you to still be able to go before turning 19.  You should also consider telling your dad that you do think you want to serve a mission, but that you know you need to prepare yourself to go.
You need to know that the Lord loves you.  You have not done anything that will keep you from His love.  His hand is stretched out still, all the day long, for you.  Repent!  Draw near unto Him.  Read your scriptures.  Pray fervently and sincerely.  At this point the only thing holding you back is fear, but Christs love casteth out all fear.  I can tell you already that even just the strength of your desire to repent is preparatory to your becoming a valiant soldier of God!  Your homosexuality, nor your sins, need to define who you are, they are merely attributes of your mortal and physical state.  You are a son of God.  His plan is for you.  Repent!  Just do it, and partake of the fruit of His love.  I promise you will find joy you have never known, or have long since forgotten.  You will strengthen your testimony, and will become a strong witness of the power of the atonement of Jesus Christ.

That is what Christians have reflected on for 2000 years. God can do anything and it is possible our salvation could have come in any fashion. God knows us, and knows our need, and has given us what we need. 
Another answer is the scriptural answer, that the OT is fulfilled in the NT, also meaning the old covenant is fulfilled the New Covenant. The New Covenant being Jesus. The law and the prophets are fulfilled in Jesus. So there are multiple scriptures that are fulfilled in the life, ministry, death and resurrection of Jesus.
There is of course a mystical aspect to Jesus and all the surrounds him.  To enter into the life of Christ is to enter into the mysteries of God.  One spends a lifetime contemplating the profound acts of God among men.

Excellent question. Allow me to speculate. from the perspective: why this way? why not just forgive people who ask for forgiveness?
My speculation (for what it's worth) is that God wanted to kick the devil into hell when he rebelled. The heavenly creatures who never experienced sin, didn't know the difference between good and evil because they only experienced good didn't understand the harsh measure and maybe the devil put oil on the fire and accused God of being unloving and unmerciful creating doubt.
And so God said, alright I will show my creatures my love, that I am merciful, that my decision to kick the devil into hell is (was) just and I as proof I will give up the most precious I have, my Son Jesus.
So in theory it is possible to reformulate your question as follows -  My inquiry for the non-LDS is more of, why was it necessary for God to use the that God used the atonement of Christ to save us?

Only if sexual pleasure were hedonistic per se. I disbelieve that. I think that sexual pleasure and satisfaction with one's spouse is a part of our divine nature.

What about this mechanism instead? If you confess Jesus is Lord [plus whatever else your particular faith requires of the sinner], then you are forgiven and saved. If you do not, then you suffer the full wrath for your sins.
This law is perfectly just because it is consistent. The damned cannot complain that they weren't forgiven while others were because redemption was made available to them but they didn't seize it. It is loving because it saves the confessed sinner from hell.
Why is a proxy death required?

@youcannotcontainme,
Usually I try to give thoughtful and sincere responses.  You deserve those from this forum, and others will give them.  However, at this time I'm going to give you some advice that I would normally not give to anyone:  Establish a pre-nuptual agreement (even just informally) to satisfy your possible temporal concerns, and then just get married!  If you feel that you love this woman, even if only like a family member, then just take to heart that many general authorities have echoed the idea that any two faithful and sincere members of the Church can make it together.  All it takes is a joint focus on Christ.
If something happened to my wife, I imagine I would be on this forum, at church, and elsewhere looking for a new righteous woman as quick as she would come to me, and take the plunge.  Of course I would seek the guidance of the Spirit in the decision, but I would be all over it fast!  It might not yield the desired results, but finding myself in your specific situation, I don't think I could hold back from marriage for very long. That could be my personal weirdness more than anything; who knows?  However, Paul even taught that it was better for a missionary or a widow to just get married rather than to burn in lust.  He said nothing about love or anything.  Pick you a fine woman who likes you and get hitched 
I promise I'm only half crazy!  
Edit:  Oh, oh!  Some advice you might more likely consider this time:  I recommend a book called '300 questions lds couples should ask before marriage'.  Just google it, go through every question together.  After doing that, if none of the answers you give each other scare the other one off, you are good to go buddy!  I am 7 years strong and that's what we did!  

I would choose the superpower of speed.  Specifically to the level of the Barry Allen - Flash.  Why?  Because if you really had the speed capabilities he had you would basically be the best, at everything.  You could cram for a test, or learn almost anything in about 5 seconds with the speed reading skill.  You could use a speed burst to be good at almost any sport.  You would be the most powerful soldier in the armed forces, or privately.  You can manipulate time, walk through walls, produce lightning, fire, and wind.  Run on water, swim ridiculously fast.  I mean, there are very few skills you wouldn't be able to master.  You wouldn't need to teleport because you could run undetectably and vibrate through solid walls to get where you need (on the planet at least).

I am not entirely certain that I wouldn't resort to cannibalism of the dead if I were in a starving life or death situation.  I pray that I never have to experience that choice, although there have been some who have.  However,  I would down your chickens without a second thought . . . in front of you . . . while you starved.  I would also have no problem drinking coffee, tea, and alcoholic beverages if it were a true life or death scenario.  Once again, hopefully I will never be placed in such a terrible situation.
I agree with this line of thinking.  However, as long as you don't try to convince other people that they should be vegetarian or vegan then I have no beef with you.  Get it beef!  Hahaha.

I don't think there is anything inherently immoral about vegetarianism. If that's a route you want to go, I don't see a problem.
For myself, if I were to decide to go to a vegetarian diet, I would make sure to eat meat every few months, just so I could honestly say I was not 100% vegetarian. In the words of Doctrine and Covenants 49:18-19,
I have no problem with vegetarianism, only with someone teaching that it's a "higher" or "more holy" way.

That's almost as weird as the pineapple must feel when it shows up on my slice of pizza.  

@Grunt, I just thought of something else and I owe @Carborendum for sparking the thought.
You said:
Have you ever sat down to question and have someone prove that Moses was a real prophet?  Or have you simply accepted that he was because of the biblical context and historical reference which is ascribed to him?  Same goes for the apostles.  Even beyond that, do you question the validity of the Holy Bible?  Some do, but assuming you don't and your work friends don't, could you or they lay before me evidence of the translation and transcription of the Bible?  Could you sufficiently establish is it unaltered, and preserved as it originally proceeded from the mouths of the prophets and apostles who wrote it?  Are you comfortable claiming there is nothing missing and no possible way there is something extra inside it?
Most Christians who answer these questions respond by saying something along the lines of trusting that God brought it forth by His hand and preserved the message His children would need through inspired individuals and despite the wicked.  I could easily say the same about the Book of Mormon.  Either way, it is the Spirit that will witness the truth.  I don't expect you to actually answer those questions, just some rhetorical food for thought.  People tend to require much more evidence from the LDS church than they require as evidence for their own faith, especially other Christian denominations.

Thank you. I've decided to continue reading the book of Mormon before I move on to other books, with the exception of essays or teachings on Scripture that help me better understand what I'm reading.  I'm only on 1 Nephi 19, but until today I spent more time being sidetracked with reading Wikipedia and websites than what I should have been reading.  Thank you for getting me back on track.
I'm enjoying it thus far, and I'm glad I decided to focus here.  You probably don't realize it, but you helped considerably.  Oddly, I also received a text from the "online" missionaries and a call from my local ones.    I will say, Nephi says "and it came to pass...." a lot.  Must have been the vernacular of the day.

Yeah, they never get to have alligator bisque or alligator boots.

But it doesn't say that at all. So how is it definitely? It says sparingly. The last I looked vegetarianism/veganism doesn't allow for the sparing eating of meat, by definition. That's like being a virgin who has sex sparingly. It's definition-ally impossible.

I know of no rule in the gospel that demands we eat any given thing. I do know that the gospel teaches us that we should be wise.
There are 5 "rules" to the Word of Wisdom. Abstain from coffee. Abstain from tea. Abstain from alcohol. Abstain from tobacco. Abstain from illegal drugs. Take care of your body, eat healthy as best you can, and be wise.
That's it. Anyone else claiming "rules" is blowing smoke.

Where's the argument?  Any pineapple that appears on a slice of pizza is clearly lost.

That's almost as weird as the pineapple must feel when it shows up on my slice of pizza.
