You'd benefit very well from 4.88 gears in that case. That's a killer setup and many agree. I'm sure Jerry will have some good things to say from when he used to run 4.88 and 35" tires on a 5-speed.
Thoughts on going to 35"s

4.88 is appropriate for the 2.5L four-banger and 5-speed for 33's. For the 4.0L engine and 5-speed and 33" tires, you want 4.56. 
I was only saying 4.88 as long as he was going with 35" tires. For 33s, 4.56 is definitely the way to go.
You've got a NV3550, see here:

So I would do 4.56 gears for 33" tires or 4.88" for 35" tires. I recommend Revolution gears for this.
You'll need an SYE (I suggest the Advanced Adapters SYE which will also come with a new double cardan driveshaft, which you'll need as well).
In addition to that, you'll also need to beef up your front and rear axles with chromoly / alloy shafts. I think everyone on here is going to suggest Revolution (and I highly suggest them as well), so talk to @Garza for a deal on those parts.
In addition to that, you'll need a new cable shifter for your transfer case, another thing that @Garza can set you up with for a good deal.
If you already have a 3.5 lift, I would add a 1.25" JKS body lift which will put you at 4.75" which should be just enough to run 35" tires, or easily run 33" tires.
The fenders will be another issue. With stock fenders and fender flares you should be fine as long as you set the bump stop properly.
However, if you want even more flex room, you could get something like the Metalcloak fenders, or a more affordable option like the Smittybilt XRC fenders or similar.

If you are bottoming out with 33's, maybe look into a tummy tuck?? If you are bottoming on the skid that is.
