I'm a game music composer & run a blog which tries to pull together (hopefully!) useful info for indie game developers. For sound effects - I created a list of sites with various free SFX: 12 Great Places to Find SFX for Games
If you want to hire a composer - these tips may help: 5 Top Tips for Hiring a Game Music Composer, and obviously, if you'd like to chat, drop me a message :-) (ninichimusic@gmail.com)
For some ideas on how to use music effectively in your game, perhaps see: 5 Ways to Use Music in Your Game
I hope some of those help!
