I talked to Chris earlier this week about writing some threads on using a DRB III for certain functions. I actually have drafts of speedometer calibration and cam/crank relearn/syncing complete as of this morning. I will be proofing them and posting them by the end of the weekend. They will be very complete for 2005/6 model years, but not so for earlier because I have only had access to my 2005 LJ. I'll be adding details as I get access to other model years.
I just posted a thread on cam crank syncing:

NOTE: I had the wrong link in this post and edited it with the correct one.
