Is it ok to replace brake calipers and reuse the pads and rotors? Or are you supposed to replace the pads and/or rotors? I sort of assumed that if the rotors and pads are both being reused then there should be no issue. However replacing just rotors and not pads is usually not a great idea since the old pads are worn to the old rotors.

Never thought about this before, but common sense tells me : pads and rotors should be replaced together, though depending on pad material and rotor surface and wear, you could slap new pads on good rotors. But if your pads are semi-metallic or metallic, you can be sure your rotors will be worn down witn one set of pads. Calipers ? They apply pressure to pads, pads put pressure on rotors, so... if your pad/rotor combo is healthy, I don't see why you should throw them away if you repalce the caliper.
Agree with @Mark_ , no reason to throw them away if they're currently fine. They should work the same as long as the existing pad/rotor set wore-down together. I'm curious though, are you replacing multiple calipers? If so, what happened/why? Frozen guide pins?
ps: Remember to check your brake code on the front. Depending on which Cherokee you have, some are two piston and some are one. All rear calipers are single piston. Also, remember in the rear to retract the electronic parking brake (via. the uConnect Service Screen)
I guess my questions would be, why was the caliber replaced in the first place? Was it sticking, not engaging, etc.? You could have uneven wear, or heated up the brakes higher on that wheel. In theory they should probably go in correctly if it was replaced before there was an issue, and the pads "should" line back up into any groves that have naturally formed in the rotors. I would probably look at it in how warn are the brakes, and how flat are the rotors. If the pads are over 50%, I would probably change them. If the rotors feel grooved at all, I would probably change them. If they are still relativity new, I probably would leave them alone if they all have the same amount of wear.

I had a sticking caliper on my F150 last year. I went ahead and replaced my pads just in case...cheap insurance. I was afraid that with uneven pads I would pull when I brake. Pulls while towing is not a good thing so spending an additional $70 was cheap enough insurance for me.

I'm going to get powder coated calipers. I'm too lazy to paint them with brake paint like I did on my last vehicle. That took me two whole weekends on my knees and pain. Since I needed to do like 4 coats and it only lasted about 5 years before it started flaking off.
I feel your pain. Knees, backs and Cherokees have something in common... Sooner or later the warranty runs out
