Does anyone know if there is a big difference between the two models? I have readily access to a 2000 XJ Service Manual and was wondering if I can use that for my 2001 XJ if needed.

Differences should be minor. You can identify the equipment on your jeep by getting a "line sheet" from a dealer or get one online at the Daimler/Chrysler web site I think.

The cherokees use pretty consistant parts over the years.

From what i've heard the 01 xj is just a left over of 00 xj's...At the time it was unsure when they would be discontinured..
