I think those CSS templates make for some of the cleanest and most appealing web sites around. Overall, I think it looks great! No shame in using something pre-built to help you accomplish a daunting task, especially if you have no knowledge of web design.

And, I use Dreamweaver on a daily basis. IMO, it's by far one of the best editors out there. There are a lot of other great apps that I use for web development, but are great for coding vs WYSIWYG...
