Did Lincoln want to abolish slavery? Yes.
Was he in favor of slavery? Not in any way that I am aware of.
Did he think there was any constitutional power for the president to interfere with slavery where it then existed? No.
Did he support a plan to re-establish blacks in Africa? Yes , at first. He later rejected that plan. It was I believe in great part to his seeing how well black soldiers fought for the Union.
Was Lincoln a racist? Perhaps by today's standards, but not by 1860s standards. If you want to truly get a handle on the views of Abe Lincoln, I suggest you read a good biography (try David Herbert Donald's) or two about him along with the Lincoln-Douglas debates and the Cooper Union address for starters. If you just want to ignorantly slander him, then stick with works by Lew Rockwell, Dilorenzo, Kennedy Bros. etc..
Meanwhile, I realize that you will just read what you want, make up what you want and discard the rest.
Abraham Lincoln, Speech fragment concerning the abolition of slavery, c. July 1858. The Gilder Lehrman Collection.
"I have never professed an indifference to the honors of official station; and were I to do so now, I should only make myself ridiculous. Yet I have never failed – do not now fail – to remember that in the republican cause there is a higher aim than that of mere office. I have not allowed myself to forget that the abolition of the Slave-trade by Great Brittain, was agitated a hundred years before it was a final success; that the measure had it’s open fire-eating opponents; it’s stealthy “don’t care” opponents; it’s dollar and cent opponents; it’s inferior race opponents; its negro equality opponents; and its religion and good order opponents; that all these opponents got offices, and their adversaries got none. But I have also remembered that though they blazed, like tallow-candles for a century, at last they flickered in the socket, died out, stank in the dark for a brief season, and were remembered no more, even by the smell. School –boys know that Wilbe[r]force, and Granville Sharpe, helped that cause forward; but who can now name a single man who labored to retard it? Remembering these things I can not but regard it as possible that the higher object of this contest may not be completely attained within the term of my natural life. But I can not doubt either that it will come in due time. Even in this view, I am proud, in my passing speck of time, to contribute an humble mite to that glorious consummation, which my own poor eyes may [struck: never] not last to see."
