* There is a light clunk sound coming from rear diff when gas pedal is reapplied. In particular after turning a corner. - Any serious issues there or just diff lash taking up?
Other than these 3 issues, vehicle operates nicely. Did notice Combined fuel usage was 14.7L/100 but I think was just to only being driven short distances last few days.
Thanks in advance.

Is the oil leak coming from the bell housing region if so you need to confirm if it's red AT fluid or if it's thin black engine oil. It is common to have engine oil slowly work it's way down from the turbo area between the V6 valley on top. If it's this it's not a big problem. If it's red Auto Trans fluid then it's a big problem to fix and just run away.
The diff or drive shaft clunk also sounds serious as there should be no noise there. It many need a new diff or rebuild, it's unlikely it's a loose drive shaft. Or there's a problem with the transfer case but I've never heard of this issue. Or I'm wondering if it's the front diff mounts torn which is very common and give a clunk noise on take off or sudden acceleration. Torn front diff mounts are an easy fix but a bit fiddly.
Service 4wd could be many things such as simple as wheel speed sensor but more than likely the Jeep N23 recall fix has stuffed up the car shifting into low. You can read heaps about this on this WH Grand threads.

Try removing fuse #25 as a simple test fix.
Aircon issue - I'm not sure but could be simple
Be warned if you need to rely on a Jeep mechanic to do the repairs it will cost you a big fortune however if you're handy and good at mechanical work you can do most jobs very cheaply as parts are extremely cheap ex the USA.
I'd be making sure this car was very cheap with such unknown and possibly major issues
