Right off the floor the JK Rubicon is awesome. It comes with rock rails, and you could either modify those or replace them. Get something wide enough to make a nice step. Really helps for a lot of things.
If you go soft top, opt up for the Premium soft top. It is really a nice difference. If you go hard top, get the headliners.
Also, at least front mud flaps to help keep the sides from getting sand blasted. Rear mud flaps will keep trapped rocks from flying out and breaking someone's windshield. Very cheap.
Also the 4.10 gears are super nice to have over the 3.73. You may pay a small penalty in fuel mileage, but the Jeep is so "peppy" with them I think you'll like the trade off.
Mopar has a "Big Brake Kit", that has a great reputation (I don't have first hand experience with it). One thing I found lacking is brake pedal modulation at threshhold. More assist would give a wider threshold, which is very helpful on long technical down hills, or tough loose rocky climbs (for suspension loading to keep momentum).
This is all stuff you can have the dealer do before you pick it up.
If you are going to get an automatic, at least get an engine / transmission skid plate. There is a cooler line underneath with no protection at all. Not hard to get a rock or stick bounced up in there (see picture below).
The stock rear bumper makes a great storage for about 7 gallons of non-potable water. I'm sure you've already got a water jug for drinking water.
I think you are really going to like the JK. It is like one great big "Easy Button", and is so stress free to operate.
There are a lot of really great builds on here, so while you're waiting for the Jeep, you might want to read through them. Some pretty talented folks have done a lot of very cool things to their rigs.
You are one lucky man! :beer:
