Dreamweaver actually ships with a lot of built-in tutorials. I would start with them...
And I would strongly consider upgrading to Dreamweaver CS3 (aka 9), I never bothered with DW8, because it generally misbehaves, but earlier this week I downloaded the trial of DW CS3, and (although it still isn't quite ready, IMO) it seems very much improved both in functionality, and - even more important - in the way it generates code...
I was planning on only buying Photoshop CS3, but now I'm strongly considering getting DW, too, or maybe even the whole Adobe CS3 Web Premium... even if it's about three times the cost of "just" Photoshop... 😱
