Looking for suggestions...

1992 4.0 leaks oil. I'm pretty sure it's the rear main, but I am thinking of taking this opportunity to pick up a gasket set from Summit and replace all the seals. If I am going to have the engine opened up anyway, are there any other jobs you think I should do while I am at it? I am also considering an aftermarket cam as well. Something like the COMP cams 4x4. Any other ideas?

When looking for an oil leak you have to remember a couple things. The oil flows two ways one by gravity and two by air flow in the engine bay so before you dismantle a lot of your Jeep check closely. You may want to clean it all up and find a fresh leak to be sure. A lot of oil leaks all end up dripping in that area mines was a bad valve cover gasket not the oil seal.

Oil pump and timing chain if you decide against the cam change.

Don't worry, i've already changed the valve cover gasket and cleaned it all up. I just got done with that little project not too long ago and stopped it leaking out the top, but there is still a leak coming from the back of the engine, and it got worse after I lifted the Jeep and the engine started sitting tilted back a little bit.
