Probably the biggest thing to accomplishing your dreams is the desire to learn and willingness to work. If you have both of those, the rest will fall into place.
Learning HTML is not necessary, but will definitely help you in the long run. For total newbs, I actually recommend MS Frontpage. It's very user friendly and fairly intuitive. Once you gain some coding ability, you'll probably end up disliking Frontpage for all of it's annoyances and limitations, then it's time to move up to DW or something else. But like I said, if you have no coding skills yet, Frontpage is pretty good.
There are a ton of great HTML books, and tutes out there. One of my favorite series are the "Visual Start" books. The HTML one is by Elizabeth (somebody, can't remember her last name), and is great for beginners and advanced users alike. A great online tutorial is
WebMonkey. It's how I started out. They start you out slow and do a great job of building on previous lessons.
On my site, I have a simple tutorial that explains basic tags and has a HTML tester, so you can play around with your new found skill. Webmonkey and W3C also have HTML testers, so that's not something unique to my site. Just thought I would clear that up.
