I would recommend the following;
- A footer on each page that duplicates the main sections of the navigations bar
- A purely HTML Sitemap linked directly from the homepage
- A meta description tag and a title tag
- An XML sitemap file submitted to
http://www.google.com/sitemaps
Google webmaster tools will actually tell you the pages that do not have enough content on them for their crawlers (ie too much FLASH/javascript etc...)
