Critique this page: Web development

Ok, so I am having problems with IE and my web project. It is a personal web page, so it doesn’t matter for the most part. I more or less just want to understand it and make it look neat. Unfortunately it looks fine (to me) on Firefox, but looks all funky on IE. Here is my test page, any suggestions or opinions are welcome:
