Well depending on what kind of driver you are, most people will suggest not to lock the D35 with 33 inch tires without doing some additional reinforcing (such as stronger axle shafts). If you have the D44, throw a locker in there and no worries. You can tell what rear axle you have by looking at the differential and seeing if the drain plug is plastic/rubber, or if it is a metal plug. If it is plastic you have the D35...if it is metal you have the D44. All jeeps (unless they are a rubicon or have had work done on them) will have a D30 front axle.
For 1000 dollars, and both axles...the only way you will really be able to go will be a Detroit locker in the rear and a lunchbox in the front. You could put a lunchbox in the rear but it wont be as strong and is typically not as well behaved on the road. A lunchbox up front is perfect. The only thing to consider is if you live in a climate that frequently sees snow, automatic lockers and lunchbox lockers can cause some ill side effects that need to be considered (ie. understeer).
