What is the best way to add a shadow to the sides of this page? (I want the peach area to look like it's popping out of the wood) - Common styling technique in web 2.0 templates.

you just center the content and apply a background to the body properties

 

I stink at this, but my solution would be to make a background image 1 pixel in height for the big white box.

 

Background image either to body or to a container that holds the content.
