That dreamweaver template way of doing things is pretty dated. Based on your post it seems like you don't want to do that much hands-on coding. I would recommend researching Wordpress for your site.
Wordpress is popular for blogging but you can configure it to run a site. It'll take a small chunk of time to get one up and running properly. Once it's up it's easy sailing... grab a free theme

some hosting companies like godaddy let you do a one click wordpress deploy.
