can't help ya with part on of yer post but for part 2..
I'm gonna be doing my first shoot sunday.i live in ohio.
the director told me no charge to view.
$15 to "play" each shoot/match. they like all shooters to a member of IDPA and thats $35 i think he said but you can shoot the first time without joining. he said if i come to watch bring my stuff cuz i'd regret not bringing it cuz i'd wanna shoot once i watched a little so i'm just planning on signing up and doing it.
it said 80-100 rd.'s and in my 45 it'd be about 20 bucks worth of ammo so thats more $$ than the sign up fee.
all the folks here said "go for it!"
hope somebody else can help ya with part one of yer post. but thats my take on yer second question
