Newbie CSS template: Needs verification on IE please

[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 the 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/images load too slowly? I am still learning...! Thanks guys.

change the width. most of the users use 800x600 resolution. The images load fast enough.

change the width. most of the users use 800x600 resolution.

that is not true.
800*600 users are below 10% now.
even yahoo's new (beta) version dropped support for them
