Take what you feal most comfortable with shooting. If it's an auto, take 4 mags if you got'em. Also, hearing protection, glasses, and water. I know the hearing protection and glasses are a no brainer, but you would be surprized.
If this is your first time at competitive shooting, just go slow. Be careful. Listen to the safety officer. If you have a doubt about anything, ASK about it.
Be prepared to have fun and get addicted to it.
"And by the way, Mr. Speaker, The Second Amendment is not for killing ducks and leaving Huey and Dewey and Louie without an aunt and uncle. It is for hunting politicians like (in) Grozney and in 1776, when they take your independence away".
