Here's an interesting article I found on how to customize wordpress for SEO.
The resource link below covers: SEO plugin recommendation, internal link structure, ping list, and other goodies.
Take time to check out the "related posts" links as well, Joost De Valk's blog features a great power point presentation on WP SE strategies.

Happy blogging.
