Details on font migration needed


I would like to migrate my font collection from 9.2 to OS X. While I understand that I will not need to do anything to the files, I am not 100% sure how to do that. I understand that the fonts go into ~/Library/Fonts/ or /Library/Fonts.

The main question that remains is, what to do about file name extensions for TrueType or Type I Postscript font files. With the Type I fonts, what would I do with the font suitcases?
