Answer 1

there is no such thing as "soundproof" it's more like sound deadening , if your willing to pay top dollar, hire an expert.

Answer 2

I "soundproofed" 1 room in my house before it was done being built. I put Insulation between the floor joists, it's worked very well.

Answer 3

The new cork flooring is about as quite you can make it. check them out, they are quite different  than you imagine.

Answer 4

You're probably better off building a sound proof studio:)
