Chameleon is a good tool, although I find advanced submitter is excellent as a hand-submission tool
As for posting galleries, I'd highly suggest against posting hosted galleries, and either finding someone to make you templates or making them yourself. FHG are more geared towards tgp owners, and the ratios they give are really not indicitive at all of the kinds of numbers you will pull from a custom template. If you need some more advice, please feel free to hit me up, icq 3522039 and I'd be pleased to give you a few hints and refer you somewhere if you need a designer
