There are loads if you include multitable SNG.
If you can, it is worth trying a few for the smallest stakes they do and seeing what you like best (try not to be too results-oriented and don't rule out a return to cash just because of your comparative results so far either)
Not sure what you mean by 'min deposit' that's up to you. If you never want to deposit again then you have to be able to beat the $1.40s (or something else you switch to) before you can come up with a number. If you think this is the case then give the kind of roi you think you can beat them for and we'll go from there. Just budget it as an 'entertainment expense with potential' otherwise.
Game selection for me was more about picking games that suited my strengths than anything else. I am less bad at the late game than the early game, I am better at a full table than a short one so turbo 45-mans were best for me. On the other hand strengthening the weakest parts of my game would probably be better for me
