Hi BlueBuddha and welcome!
About TGP's: Not really sure what is your question... Galleries are submitted to TGP's according to the rules of TGP. Reviewers decide if they'll post it on TGPs or not. You should not try to post the same gallery twice to the same TGP. As for "newbie treatment" - it varies from TGP to TGP. If you make good galleries and TGPs don't have enough quality submitters, your galleries will be welcome.

Paysites: You should wait for a while until you get more experience with adult sites. And it isn't about amount of traffic - you need the good adult webmaster knowledge before starting investing into this biz.
I would recommend you to start with building free sites. It's a bit easier to handle than galleries. The good thing is that you are at the right place for free site building info. Read this board, build a site or two and post here for review. You'll get lots of good info which will be enough to get you started.
Good luck!
