Honestly, my suggestion would be to learn some basic HTML, then move on to Dreamweaver, or stay with a standard text editor. You'll find it much more rewarding if you know WHAT you can do, other than trying to figure out if you can do it, then trying to figure out how to do it. With this, you'll be steps ahead if you want to start to use CSS, XML, PHP or other website enhancing dodads.
Your site looks spiffy, but none of your links work, but since it's off a template, you probably know that.
Here's some great links theFez posted earlier in the homepage thread:
http://www.alistapart.com for good css information (kind of advanced)
http://www.w3schools.com for good basic html/css/javascript information. they have a 'sandbox' environment where you can play and see what happens.
http://www.htmldog.com/ is another great reference for css and html
http://www.phpfreaks.com/ for good php information
Whichever way you go with it, good luck and feel free to ask questions as you have them.
