Not that "difficult" just time consuming and a bit harrowing because you need to grind the output shaft and its much easier in the vehicle.
For the driveshaft, if you have an automatic trans (aw4), you should be able to re-use the front driveshaft on the rear. My recommendation is use the front shaft as a temporary to check fitment and length, and either get another front shaft from an XJ, or get a longer one from a ZJ or WJ with the Double Cardan front shaft (Mine was from a WJ and was close to 33.5" when centered on the splines). Or order a custom HD shaft from Adams, Tattons, Tom Woods, or any of the other reputable driveshaft builders but wait until you install the SYE and then take measurements, otherwise you are kind of guessing at the length and won't know for sure, especially with a hack n' tap kit.

advanced adapters also makes one--but the they are $500. Lots of people run the h&t with no issues. Not sure if the AA is worth the extra $$

I've been putting off doing mine for some time now. I have the parts sitting in the garage but just haven't had the guts to cut my output shaft yet. I think cutting and tapping the output shaft is the hardest part. Some videos I've seen the people take out the transfer case and do it but that's a lot of extra work. It only makes tapping it easier, which could make or break the mod if you don't tap it straight. Cutting the shaft looks easiest while it's still installed and you run it. I was told to run it in reverse when it's being cut.

buy the Iron rock offroad drilling jig works great... use a fresh drill bit & tap slow.

Have the IRO Hack-n-Tap in my Wagoneer with a NP242, was fairly easy install once I got over the whole got to saw off part of my transfer case fear lol. I'm running a shaft the same length as the factory front shaft, 90 Auto 4.0L.
