Just bought a 98 Cherokee with 61k miles on it
Have no idea of past service record, I am sure it has been doing a lot of sitting around, what would you recommend in terms of fluid changes, and or flushes? Thanks

I would change every fluid that there is. The one thing about buying a very low mileage vehicle is that you can't tell how long it was sitting for before you picked it up. I would pull the valve cover and see if there is any surface rust forming on the rocker arms. Was the jeep in a garage out of the elements? Where are you located? I would look for rust and check electrical and ground connections too.
Agree with the above. Oil/diff fluids, change em' out. Couple things;
Drain some transmission fluid (Dex III) using the drain plug. You won't drain it dry, it will just remove a quart or so. Add back the amount you removed then drive it around for a week and repeat. Do that 3 times or so and you will have changed out the fluid hassle free and w/o risk of major shock to the system.
The cooling system on Cherokees can be iffy. A flush and fill is a good idea. Low pressure, nice and easy but if it's been sitting or rarely used I'd get new coolant in it.

Something i have always done,When i bought something used but new to me i do a full tune up a new battery and change all fluids from the oil to even the brake and power steering.This way i know everything that should be changed has been and its got a clean start so no break downs or problems.

Plus change the gear lube in the differentials also, if fact a couple of oil/filter changes in the first 1500mi. would be a good idea to clean it up also.
When cleaning/flushing the cooling system don't forget the heater core as well.
