Hi Shane,
to answer your questions:
1. not sure I think you just pay for the membership and you're on board
2. Full on summer boardies and a rashy, full on winter 4/3 wetsuit and booties, in between depends on your tolerance to either heat or cold
3. Do you mean local sources or just in general? In general: There is this website...you...something, you...pipe, ah, I don't remember!

Have fun, it's the best sport I have ever tried,
See you on the beach, Eric
