Flash navigation and SEO

I have a bit of a dilemma!

I am designing my website to promote my design work and at the same time would like to learn more Actionscript 3.

I would like the site to be successful in SEO and think the navigation would look best in Flash, however would that mean using frames for the HTML, which would then mean bad SEO?

If I built the whole site in Flash is it true to say that Google can crawl it, however other search engines won't?

Would I be better off building the site in HTML with a simple navigation and use a few Flash pieces within the site?
