Whenever you have specific questions, we'll still be here.
I still suggest studying sponsors is the place to start. Those are the people who mail the checks.
Since you may not want to get involving in buying porn content to use on your pages, you'll want to find a sponsor with plentiful free content that you can use to build with.
I also suggest studying "traffic sources" - those are the bigger sites we get surfers from to look at our little selling freesites and gallerys.
Greenguys's page here
http://www.link-o-rama.com/greenguy/mlinks.htm is a goodplace to study a traffic source. You want to click on the links on the right hand column - the new porn links page is a place to start
http://www.link-o-rama.com/greenguy/newsites.htm
Studying this will help you see what a small home adult webmaster does to make money - which includes building freesites.
All these people talking about starting with blogging are nuts - it's a terrible place for a beginer to start.
Summary - #1 we'll be here, #2, study sponsors, #3 study traffic sources.
#4 = Study for a while.
