FF and IE viewing problems

I’m currently making my site’s layout, so the HTML/CSS isn’t that clean yet, and I don’t want to hear anything about <table> vs. <div>, so, yeah.

My problem is that, in IE, the two bars on the far side of the white area have a td background=”__” property. That shows up properly, but they should span more, as the table is set to 100% height, and the second tr has a defined height of 320. Also, in the white area, my repeating background (#content) and my bottom right background (#overbg) don’t go all the way to the bottom. Firefox, though, displays this correctly. Additionally, if anyone knows how to get rid of the < ul > and < li > in the sidebar, post that too, please.
