Well, you have this set:
<TABLE border="0" cellpadding="2" cellspacing="2" width="100%">
in your menu.tpl. That is pushing the table out in either direction. Try removing the cellspacing and padding and see what happens.
Oh, and kill the music...nothing more annoying than getting blasted with music when you open a site and not being able to stop it (it restarts itself over and over in Firefox no matter how many times you push stop)
