There are probably millions of pages on the web that will show you all you need to know. Search engine will give you more than you have time to check out.

There is also Youtube. Just look around

Yep - the web is your resource =). To add on to Ron, if you're completely new to WP, you can watch youtube setting up WP videos, and basically take it from there. Whenever you have a question, you can google it, or ask a question here. I believe that the best way to learn is just to jump right in and play around with things.

A great site to use would be wpmudev.org, great resource.
