Bathroom Colors?

I ordered a high gloss, white vanity + black granite countertop for my bathroom. The shower and sinks are white. The facets are chrome. My 3 questions to you are:

1. What color and type of flooring would you recommend? Could the flooring be "shiny" such as porcelain tiles (I like that look) or should it be a matte finish?

2. I love glass, linear back splashs; does this sound OK and what color do I go with: black or white?

3. What color would you recommend I paint the walls?
