The main problem in IE is that you don't have a doctype and without it all versions of IE will go back to last century and behave much like IE5 and render in quirks mode using the broken box model.
Add a current doctype such as this to the top of the page:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
That must be the first line on the page and there can be nothing above it (not even comments).
Your page is using old fashioned code you would do well to bring it up to date a bit and lose the tables, font tags, breaks for spaces and stylesheets in the body. We can help you with that if you are interested in learning best coding practices
