2x4 is fine.

2x4 interior walls are fine. I used 2x6 and added sound absorbing insulation. Just a thought to consider. The cost really is minimal when you look at the "big picture" and you may appreciate the difference. The 2x6, however, does cut the space down a little. Even if you choose 2x4, I'd suggest the sound proofing (I like Roxul).

2x4's are fine for any interior walls.

Be sure to use blue board instead of normal drywall on any walls that are near moisture.
