Try this CSS - I fixed a few things for you using FireBug.
The whole thing now center aligns properly, I cleaned up SOME indenting. I removed a few missing images. I neatened up the code (missing semi-colons, etc). Added a little padding... Looks better imho.

Try to consistently use either spaces or tabs. People tend to prefer spaces as tabs can look different on other people machine's. The Drupal standard, for example, is that an indent is two spaces. I've used 4 in your code above where I could.
