Answer
Nathan,

If you want to do the more extreme trails like the Rubicon, then you would need a minimum of 31" tires, and at least one locker.  33" tires would be preferable.  The main problem with the Cherokee, as far as large tires go is that they don't have large enough fender wells.  If you plan on going with 33" tires you should consider cutting the fender wells, and putting on a new set of after market fender flares.  I would suggest that you consider installing a lift that would work with 33's instead of 31’s, usually a 5” to 6” lift.  One reason is that the 33's are more common on the extreme trails, and you need to remember that for every inch of diameter on the tire, you only gain 1/2" of lift, as that is the radius gain of the new tires.  Most of the drivers that I know that have went with a smaller lift, eventually upgrade to one that will accomodate the 33's anyway, and it's much cheaper in the long run to lift the Jeep once instead of twice.  

A site you may want to check out, is:
http://www.jeeptech.com/tire/  
They give some basic suggestions as to what size lift, and what modifications are needed for a specific size tire.

As far as which lift to purchase, that is a matter of personal preference. Remember, you get what you pay for.  The cheaper lifts, usually are not as well designed, or not as complete as a more expensive lift.  This doesn't mean that you need to go out and buy the most expensive lift that you can find.  You can find a middle of the road lift that will work just fine.  Purchase a few 0ff-Road magazines, such as JP, 4-Wheel Drive & Sport Utility, and 4-Wheeler to name a few.  Go through them, and check out the ad’s for lift kits, tires, etc.  This will give you an idea of costs.  You can call most of the advertisers, and talk to their tech departments to see what will work for you.  A couple of the parts distributors to call might be Quadratec, or 4-Wheel Drive Hardware.  They sell a wide variety of lifts, and have a fairly knowledgeable tech department.  They, also have catalogues that are specifically for the Cherokees.

The main thing, whatever you do, make sure that it's what you want, and that you enjoy it.  I know that this answer is fairly long, but it’s hard to discuss this subject without going into some detail.  I hope that I answered your questions for you.

Will discuss suspensions, lifts, lockers along with tire suggestions. Trail ratings and possible requirements needed for specific type of trails. Safety equipment and what you should carry with you. Certified off-road instructor. I am not a mechanic, and 4-Wheeling is a hobby, so if I can't answer a technical question it is due to my mechanical knowledge being related to vehicles that I have owned, or have worked on. I do not have manuals on all vehicles.

Experience

40 plus years of 4 wheeling in a variety of vehicles. At the present time, my major off-road rig is a 94 Jeep Wrangler with a spring over and a 1 1/2" suspension lift. This gives me a total lift of 7" or so. I have lockers front and rear. I have removed the track bars, and sway bar for maximum articulation. I am running a stock 2.5 ltr 4 cylinder with a Jacobs ignition along with a cold air high flow filter. It has 4.56:1 gears with a Dodge NV4500 transmission along with a 3.8:1 Atlas II transfer case. This gives me a final ratio of 105:1 in low gear/low range. Other vehicles I own, are a 96 Ford F-250 with a 6" lift, posi rear end, 36" Hummer tires, 5 speed with a fuel injected 460 ci engine, an 87 Samurai with an 8" lift, Ford 9" rear end with a spool, Chevy Dana 44 front end with an electric locker, 5.88 gears, 16% reduction in high range and a 6.5:1 low range with 35" Baja Claws, and a stock 2003 Grand Cherokee Overland. Trails I have run are the Rubicon (10 times), Dusey Ershim, Fordyce Creek trail, McGrew trail, several trails in Moab, Utah along with local monthly runs.
