I don't think you're going to find detailed instructions, but if you've got mechanical experience it shouldn't be too hard, just time-consuming. Be careful and remember to watch carefully where everything goes as you take it apart.

Go over to Jeeps Unlimited, and PM a guy who goes by the sig of "Silver XJ". He has a write-up on how to R&R the evaporator on a 2000XJ, and almost all of that procedure applies to the heater core as well.
I don't own an XJ any longer, but I still think they are the best of all the Jeep products ever made. My XJ was my favorite vehicle in my 50+ years of driving.
So...I stick around and give advice.

Basically you need to remove the steering wheel and column, center console, and the entire dash. The only special tool you will need is a steeringwheel puller, the rest are just hand tools. It took me about 4.5 hours to remove the unit and 3 hours to put everything together again. You will need 2 people to remove the dash, it's bulky. While the dash is out you may want to tighten all the screws down, I was able to get rid of all my dash rattles as an added bonus.
