The list is pretty good and some things would probably need a little more clarification. I'll only point out and clarify on some of the items, but I would have to pull out some of my old second coming notes for some decent scriptural references. I basically made this post off of deseretgov which did a good job turning the list into some form of a chronology and I agree with most of his assessments.
2. Light of Christ - to live [ Probably refers to parable of 10 virgins and the need to be prepared and attentive to the holy ghost ]
3-4, 7 are probably in preparation to the restoration, but i doubt there is much scriptural reference for them if any. 7 Most likely refers to Nephi's vision of the coming forth of the Holy Bible.
13 Messenger to precede second coming [Refers to Joseph Smith preparing the way for Christ's return. Malachi 3]
14 Church and kingdom set up again [ refers to the Kingdom of God on earth being set up which has occurred and to the Kingdom of God in heaven which will occur when Christ returns ]
18 Times of Gentiles fulfilled [ 1 Nephi 13:42 and 15:13 The Gospel first went to the Jews then to the Gentiles and in these latter days the Gentiles are to receive the Gospel first then the Gospel will go to the Jews. ]
19 Judah returns to Jerusalem [ Exactly as it says, the tribe of Judah is to return to Jerusalem and gather before the second coming. It has occurred and is currently occurring]
39 Apostate [ i am clueless ]
49 Wicked to stubble [ at the second coming the wicked and proud are to be burned as stubble. Malachi 4 ]
50 Final Restitution [ Probably refering to Acts 3:21 ? which signifies the restoration of all things, which is still occurring ]
