Renton's guide is good. I think you could tighten up a little from there though, because so many micro-limit players are calling stations and won't respect your c-bets. ABC poker is right, big bluffs are almost never called for, unless you run across the rare micro-limit nit. Work on getting reads, writing notes and using those to cater your play to specific opponents. I would add tables slowly, making sure you can still pay close enough attention to get reads as you're doing it.

Welcome to FTR, good luck and keep posting.
