Copy website layout using DIV/CSS

Hello SIMPLE PROJECT! I need to copy a website (I will give you a screenshot) and convert to html page using only DIV/CSS. Tableless design. I have done about 50% of the work done but I dont know enough CSS to get it perfect. Also my design doesnt work right in IE8 due to border-raduis CSS. Only need to do one psge. I will be using PHP INCLUDES to insert other content and duplicate the page. The center DIV (wrapper) in the page should be set to expand automatically once I insert my Php include statements. Should work in all major browsers. Attached Images: [login to view URL] the way it should look before.png. what i have done so far.
