For modelling I'd go for a program that will do everything you need in one package. Silo is fine but doesn't do animation for example. Modtool is good for beginners.

Softimage Modtool, Truespace or Blender.

Magix Music Maker is the best for music I've found.

Makehuman might be useful to you, if you want a Daz 3D style character creator. It's free.

The Game Creators is a useful site, they have some useful tools and content packs.
