You made SWFs for the main navigation? Why? If you did it to get a special font, use SIFR. Search engines are getting better at understanding Flash, but I still recommend sticking with HTML wherever possible (especially for main navigation).
Great intro flash animation. I’d recommend having the "mouseout" be a smoother withdrawl instead of the instant disappear… maybe reverse your "mouseover" action.
Not bad. Personally I’d make the font a little darker (if not black). Lighter fonts are better for younger audiences, but since you’re focused on companies, you might want to make sure the font is easy to read for older viewers.
