1 - You need a DocType decleration.
2 - Go away from a table-based layout and go to CSS and div tags. Will make the site much more flexible in the future.
3 - Definitely add some text to the home page. To go along with what bullitt21 said, you want to optimize your site. Your keyword meta tag will help, but you always want as much as possible. Just google "SEO" to get more info.
4 - Needs some sort of background color or image. Site seems a bit sterile at the moment.
5 - The menu/header area shifts (in Firefox at least) on the Contact page.
