Don't worry about duplicate textures. as long as they use the same flag, Blitz will automaticly optimize recognize redundant data and use instaces instead. The same goes for Sounds.
Yes, using 512 Textures is enough in most cases (esp. for tiling map textures) because even when you are very close to the wall (or whatever), the 512 Pixels are pretty close to your max horizontal screen resolution. 1024 Textures may be used for a few hi-q Characters only.
I think 120 Megs isn't a lot these days. Well, if your game is crap, then it's too much :)
