Just a nitpicky thing... is the bullet supposed to be underline in the navigation menu? Cuz the · is currently within the link. I would suggest moving it out.
(Or even redoing the navigational menu as a list and doing the mouseovers thru CSS. it'd cut down on filesize, and changing the menu would be a snap. Just add/replace/delete <li>'s as needed.
