IIRC (its been about 1.5 yrs), on the I6, you have to remove the flywheel cover plate (where the starter is), the starter, you have to raise the engine (maybe not if you have a lift, I did this before lifting my jeep) which means disconnecting the motor mounts, then remove the pan bolts.
I thought I could do it without raising the engine, but the pan hits the front axle housing and hangs on the oil pump pickup. The V8 may be different, I'd suggest looking at the Haynes manual, as it has all the needed steps with nice pictures.
Oh, and make some "pegs" by buying 4 bolts that will screw into the pan mounting holes to assist in reinstalling the pan - it helps a TON.
Oh and I also had to disconnect the exhaust...
its a bit of work, I did it to replace the rear main seal.
