Like he said, ask lots of questions. Get involved in the other sections of the forums (Basic discussion, New divers) with posting questions, reading lots of existing questions, etc. I'd also recommend renting gear for your training, trying a couple different brands of wetsuits and BCDs. Before buying a BCD, trying renting a back-inflate BCD and backplate & wing (you can google "bp/w" for more info). Lastly, don't skimp on regulators. If you buy used stuff, have it checked by the LDS before you use it underwater.
