for the good list of tgp/mgp sites, check out Chameleon Submitter (
www.chameleonsubmitter.com) - its database will save you weeks spent looking for individual sites yourself - all sites you need are inside, ready to use. It updates daily and sites in there are set up individually according to their site rules so you dont need to review rules of each site yourself.
I also definately recommend you to find a way how to make your own templates and you should also consider own hosting for your galleries.
