Short general answers, no, no, yes. For class issues you should get a rule book [will need it for safety regs and event procedures anyway] and read, read, read. I would advise ordering an ECTA book now [ecta-lsr.com] while waiting for the LTA book to come out [see LTA rule book thread in this section of the forum].
Hope to see you having fun this season, great event, greater people.
