You don't need a super Jeep mechanic for any of those mods necessarily. There is a good shop in Weymouth called Truck Guys. It's also an Audio shop, but their showroom is full of Jeep and Truck gear. They do all the installs in a large shop right at the store. I've picked up simple things like lights, deflators, etc from them. Nice people. They could take care of you very quickly I'm sure.
