Do what you enjoy the most, but do it within your bankroll. Poker is not and should never be approached as a "get rich quck" plan. It's like anything else in life, the more you put into it, the more you will get out of it.

If you play limit, I would get 500 (minimum) together and put it on party and play .5/1. There's nothing wrong with whoring it either. Party is the best (IMO) to whore a bonus.

If you are going to play ring games, try to always play with a bonus under you (unless you have rakeback). If they are going to pay you extra to do what you are going to do anyway, there's no reason not to take advantage of it. Money is money.
