Oh, yeah. And welcome to the sport and the state.
As far as what you actually want to know:
Search for whatever questions you have, if you can't find the answer, then ask.
Rules/regs will be different at every game. Ask the game organizer about them.
Rule of thumb, call your hits, don't call others' hits. Be respectful of the game, yourself, and everyone else. Bring eye protection and use it. Follow the rules and don't cheat.
