Don't know about the compressor, I carry a portable one.
Since you got a HEMI like myself, you can get the Superchips Flashpaq tuner from the States, which will give you some more ponies and tighten gears. Must have.
Also, go to an exhaust shop and gut out that stock Chrysler muffler and get a hiflo Lukey. It only cost me something like $150 from memory. Big difference and I love it. Here's my video:

We know that the aftermarket support isn't great, but there ARE ways to get the upgrades done.
You should also install a catch can. I just emptied mine again last weekend. So glad I'm saving the engine from that gunk.
I also built my own rock sliders. There's a thread on here somewhere (edit: try this:

I've also raised mine to 5 inches of lift and running 33" muddies for wheeling but running around with 31" muddies.
