Blue Ox towbars and baseplates are competitive with any of the other major vendors. We've used them since we got this rig, and we're on our fourth toad with BO baseplates. I would go with Blue Ox for the baseplate and tow bar.
My installer (in Austin, TX) makes up his own wiring harness cheaper than the kits you buy from BO or other vendors. If you don't want to go that route, CoolTech has a wiring harness for Wranglers that's supposed to be very easy to install. Wranglers are nice in that it's easy to run wiring through the car since you can pull up all the carpet easily.
You should get a brake system. I can't recommend any since the one I use only works with an RV with air brakes (which I don't think yours has).
