Styled Tables to Pure CSS?

[ne_plus_ultra]

I created a splash page with css-styled tables. I am trying to convert to a pure css layout.

- Current design is here (http://s215038318.onlinehome.us/design.html).
- Current css is here (http://s215038318.onlinehome.us/design.css).

My guess is:
- Start with header/content/footer?
- Within the content add 2 separate divs?
- How do you create a css shadow for the left/right sides of white area/container?

Considerations:
- I want to make it a 100% height css design - where the footer is always at the bottom of the page. Realizing I need to conquer the prior conversion before tackling this...

Any suggestions from css pros out there? I am a bit stuck on this.
