Versus Template

I have a few questions about the Versus template. I need a one-page design for a landing page. Versus is the best one for my needs and I need to know if the:

  1. Black photo background image can be changed to another picture of my desire?
  2. If so, what size stock picture should be used to cover the entire page?
  3. Additionally, can the portfolio image boxes be changed to a different grid design?
  4. And, can the other pages be removed permanently (about us, contact us, etc.)
  5. Could the get quote form be edited to include (name, email, phone number and the ability to add a drop-down box for choosing which state our audience lives in)
    Thank you,
    J
