Yes, the emblem is a direct fit. Black is the only color that's still available. As for all the rest of your questions... put them all in one post... easier to track that way.
The column isn't the big iddues, the wire harness is different, IIRC. I don't know if they're different but in '89 and newer progressive power steering was an option so you may want to try to avoid a column from such an equipped MKIII.
