Go to
www.uspsa.org and use the "club-finder" function. Find your nearest USPSA club, go, watch, ask, join, participate, compete, ENJOY!
Most clubs love new folks, and have "new-shooter"-type programs or mentoring to assist new folks in being safe and comfortable.
The enhanced gun-handling skills learned are priceless.
The only gear you'll really need are some extra mags and carriers, a good belt and holster, and reliable ammo. Usually someone there will lend you gear until you choose what works for you.
I'm sure you already have and use eye and ear protection.
