One thing that will speed the job up is that you don't need to jack the Jeep up to install new shocks. The last 6-8 shock installations I have done on my TJ have been with the tires on the ground. Turn the front tires to the side to provide full access to the mounting bolts.
The front shock's top nut will spin the shaft if you don't hold the shaft so just hold it with pliers while you unscrews its top nut.
For the rear shocks, you will need probably 18" of extensions between the ratchet wrench and socket so you can reach the top two bolts. If you live where the roads are salted those top mounting bolts might be hard to get out due to corrosion. If you do live where the roads are salted, either spray the top bolts a couple times with a penetrant like Liquid Wrench, Kroil, or Break-Free ahead of time to make getting them out easier, or consider having a shop install them.
