Hi there - thank you for putting your site up for review.
Cellpadding is needed throughout the site, on the right menu and the nav bar. When I look at this site, I get kinda dizzy. I dont know if having the menu direcly under the nav to the right like that would really be constituted as "good design". Especially when the page is aligned to the left. You may want to consider reworking your navigation. That's all I can remember right now but I'll check it again later.
