I can teach you CSS right here if you like...just ask away. I didn't know how to use it a few months ago...but this guy, Page, from this forum recommended it. And man, I haven't done a webpage/site without it since.
Dreamweaver...go to Kirupa.com
edit: never mind, I just noticed what Joe Dirt posted. Yeah, definitely check out Sitepoint, it's a really great resource.
