>>I know nothing about backend stuff
You don't need to know anything really. If you're on a hosted solution at blogger or wordpress.com (either using a subdomain or your own domain), you don't have access to the backend really. If you host your own, most hosts offer something like Fantastico which gives you one-click Wordpress installs, and then almost everything else for WP can be managed from the dashboard, including installing plugins and updating the core backend.
I just spent the morning with an author who I helped get online with Wordpress and he's been blogging up a storm, customizing his site and all that and just today I found out that he doesn't know what FTP is.
>>make a blog look and feel more like a website.
What, to you, is the difference between a blog and a website? To me, a blog is a subcategory of website. Websites can be blogs, forums, storefronts, brochures, portfolios, etc, etc, etc. And in fact, all of those can be run off Wordpress except forums, which can be run off a WP sister product.
