I've got all sorts of supplements for my 98 set, they cover the 5.2, 5.9 (I think), 2.5, and maybe even diesel motors in extreme detail. There is also a supplement for the ABS module that is sorta year specific, I have one for 92/93 Jeeps. I believe you could also get the errata docs and late additions as a separate book instead of the regular paste-in sheets but I am not sure.
EDIT: yep, TSB book, powertrain diag procedures, body diag procedures (basically just big flowchart books), 2.5/4.0/5.2/5.9 powertrain diag procedures, tech supplements and revisions. There was also an AW4 book separate IIRC but I did not bother getting it, and I didn't need the ABS book for this year.
