Also try contacting your local gun ranges and the CMP. The CMP used to run a nation-wide "Postal" match for air rifle which was pretty nifty - but I believe it was oriented more toward youth shooting.
My previous gun club in FLA ran a air rifle program for the youth, so local gun clubs could be a good source of info - even if they don't have a "Program" they probably have members who might be willing to work with you.
Depending on your age, you might could get involved thru 4-H as well, my son shot in their Nationals back in 2004.
