Well, apart from talking about the factors of each media, you haven't really said what help you need. If you need a good movie maker, then try (url="http://"http://www.pixels.net")Pixel3D(/url) or (url="http://"http://www.strata3d.com")Strata 3D(/url). Both are freeware 3D programmes although the UI on both is a little strange. If you want to shell out some cash for a 3D programme, I recommend (url="http://"http://www.hash.com")Animation Master(/url), it's a good programme available for $299.
As for music, i can't really help you there, I myself am looking into some nice atmospheric music, as I don't have the resources or the talen to making that kind of music. If my game used Hip-Hop music, then maybe...
