No personal information is recorded really, other than your name and 'Screenname'. You meet an AV rep and show some ID to prove you are over 18. Then the rep forwards your name/screenname to the site staff.
In the mean time, read read read. Also, feel free to ask questions about different brands of guns or things to look out for in certain brands/models. We cannot tell you where to buy them, but we can give you recommendations on which brands/models would be best for you.
You can also start gathering up the basic gear you need to get out to a game (eye protection, boots, gloves, vest).
