Welcome to GFY!
You can learn a lot here. RevShare Hosting also has a lot tutorials to help you get started and it doesn't cost anything to sign up, with no obligations after you do.
Another good resource to look at is Adult Webmaster School at
www.adultwebmasterschool.com which will also help you get going.
Of course, the best advice is to ask lots of questions!
Good luck and welcome to the biz.
