Stick or auto? Bumping up to 33's will pull you out of the power band on the freeway. Not too bad with a manual, you just don't use fifth. Auto, life will not be as fun. Then you open the regear can of worms.
If I wasn't running severe trails, I would do some of the prep work for later mods. I know I will get flamed for this, but this is what I would do.
Rock sliders. You will need them, and can use them in your current configuration.
Body lift, tummy tuck and sye. This will get the belly of the jeep up and give some more clearance underneath the jeep. Again, you will want this in the future lift/mods. You will need a motor mount lift and a cable shifter for the transfercase.
Sway bar disconnects of some nature.
Before you buy a winch plate, you can get a decent new bumper for not much more. I have an eag bumper, it has an integrated winch plate and it has been a great bumper. It was around 200 bucks on amazon with free shipping.
Winch. The badlands from harbor freight has been getting good reviews.
Fire extinguishers, but you already have some in your jeep, right? Add a shovel also.
LED headlights. Worth it if you want to drive at night.
If you aren't going to tow, ditch the receiver.
And for anything you buy that may be contacting rock and getting scraped, don't pay the premium for power coating. Paint is much easier to touch up.
I think you are local, pm me if you want to see some of the bits I have on my jeep.
