Greetings, alc.
Wow. (That's my reaction to your post. Lots of questions there.)
OK...first, you need to know how to crawl before you walk before you run. Please read my thread on "why build an adult freesite?" This is the ultimate in "crawl" threads, as it focuses only on the "in general info" and halfway down the index.html page.
I want to start you out with learning how to build one freesite and submit it to linksites. We'll work on that one freesite bit by bit and you'll learn to build it and perfect it, and as you do, you'll learn about sponsors, traffic, SEs, etc.
After you've read, buy content. About 20-24 pics, all in a set.
You can get cheap content packs here:

(It's where I get mine. Cheap, good, immediate download.)
Once you've picked out your pics and decided what kind of site your making, we can talk about the right sponsors, etc.
