I DD my 4-door kick on 29" M/T tires and OME 1.5" lift. It's the best "small" lift out there, as it's the only one that gives more flex. Bad news is it's the most expensive |removethispart|@ $800. You can do spring spacers, strut flip and new shocks in the rear for $200 or less, and you can always trim the fenders too (this looks clean, and keeps a low cener of gravity). I wheel the piss out of my setup, and it's only stopped by the harshest of trails (Rubicon). It does creek / mud crossing, snow, sand dunes, rocks... and I'm not even locked front or rear. Toss in some lockers, and it would be even better.
I live in the foothills, so I wouldn't go bigger than 29" tire. If you live in the flats, you can go bigger. The weakest point of trackers is gearing options. Other than that, they're GREAT. Good gas mileage - yes, that means the engine is weaker, but with gas prices, I'll deal with not flying down the road. Gas mileage, storage space, and ride quality are miles above samurai.
You're on the right track with All Terrain tires. These trucks are light, so you can get a generic tire, and it'll last a long long time. I like Pep Boy's Dakota brand. Search my name, and "dakota" for more on my build.
