If designed properly, the order of your XHTML will matter very little when seperating layout from content. Also, designating many different div tags as wrappers is needless in most situations. You just need to think through a layout idea before coding a single line.
Regardless of where the information for a page comes from, you are always in control of how it is rendered to the browser. The rendered XHTML, CSS, and Javascript is where the seperation of layout, content, and behavior is helpful.
