A hand with IE problems.

I have a Wordpress skin that was coded just over a year ago by Garrett. I only recently decided to start using it, and have found that the site looks absolutely great in Firefox, Safari, and Opera, but is completely ruined in IE (not just a little bit).

I was wondering if anyone could shed some light on the coding issues that are causing it to display incorrectly?
