It's a Matter of Opinion:
The maintenance you want to perform is all quite straight forward, no magic involved; however, I would recommend against the tranny flush. It's of no real value even if the fluid is a bit contaminated and often causes more problems than it is supposed to prevent.
Drain the tranny and torque converter, clean up the pan magnet, install a good filter (don't leave the old seal in by accident), change the pan gasket to a neoprene item, refill with Mercon V or Chrysler ATF+4 and go.
BTW: When accessing the torque converter drain plug be certain to turn the engine clockwise as viewed from the front, the normal direction of rotation. I use a large flat-blade screwdriver to engage the teeth in the flexplate ring gear to drive the converter around for access to the plug. Replace the plug, 1/8" NPT, using a little thread sealer.
I don't know about the front differential or transfer case, but the rear differential lube should be specified on a tag attached under one of the cover bolts. It should read, "75W140 full synthetic only", or something to that effect, in API service GL5. If the differential is a locker, then some friction modifier is required. The owner's manual should tell the amount and the spec.
You can save a few bucks by using Wal-Mart Supertech 75W140 GL5 full synthetic, ~$10.50 a quart, about half the price of the majors and just as good.
