Newbie CSS site: Needs verification on IE

[drmaximus]

This is my very first CSS website, and my first web design in years.
I designed it on my Mac, and it is fully functional as intended on Firefox.
Could somebody please tell me if it shows up okay on IE and other browsers? Something tells me that it's going to turn out horrible on IE...

Design-wise, it has to be uncomplicated since it's my first try, but I would appreciate some constructive feedback on the CSS (quoted below) and HTML codes. Also, do the pages load too slowly? I am still learning...! Thanks guys.
