Welcome to the High Road tparker,
Myself, like TrapperReady, like longer barrels on my shotguns, but like Onmilo said if you are going to be hunting brush and thickets the shorter barrels are nice but not manditory.
If you plan to bust clays and birds the longer barrels are better IMO, but even a 26" barrel is about the same as a 28" on an O/U. So whatever feels right to you when you handle the gun is what you should get.
By the way, whereabouts in N Indiana are you. If you are interested in clays, I shoot at Warsaw at Kosko Conservation. Skeet, Trap, and 5-stand.
