Well you’re off to a very good start, doing that course and all. I’m not exactly sure what you’re looking for in terms of advice, but try and scrape together 400 bucks or so for a sport-climbing kit.
Aside from that, take a trip to Boulder Rock and try some of the routes in the mini-guide, it’s a good way to get your head around granite holds (or the lack thereof). The hardest thing to get your head around at first is something 5mm on granite might be a half-decent hold, but yeah, a day of bouldering on some thin stuff should sort you out. 🙂
