Where around or in KC can I find a lids locker room, or similar sporting goods type store that sells team items?

Oak Park Mall, Overland Park Ks, not to far from where you at

5 minutes away

There is a Kid's Foot Locker and a Foot Locker in the Landing Mall. You can also go to Foot Action USA on 31st and Prospect. I hope this helps.

Overland park mall...

Annie's

Up the street from the landing mall. Its called urban gear. They sell everything.
