USPSA or IPSC, which would fall into something like that category your mention, would require safe ammo, holster that covers the trigger guard, five magazines and a gun that is 9mm or larger, and mag pouches. There are several divisions based upon what type of handgun you are shooting. Production, single stack and Limited 10 are the divisions that are easiest to start in. There are clubs at Fort Wayne and Warsaw that hold matches and are near you.
WWW.uspsa.org is the website for the national organization. There is a club finder function on the site that can give you contact info for the club president. Getting started is easy just show up. If you were closer to Terre Haute I would just say come to our match this Sunday and we would get you started. It is probably too long of a haul but you would be welcome.
