I did this last season on my 90 Indy 500. I don't have any tips except those 1/4" bolts strip out really easy. It is kinda stupid that you have to take so much crap apart just to get at the stupid brake pads. You can't cheat and try to weasel them out of their either, I tried.
One tip I would give you is to put in the heavy-duty brake pads while you are in there. They make one set of normal pads and another set for sleds with studs. Put in the ones for studded sleds, they last longer.
Is it really that XLT's are different, or is that the chaincase changed? All Indy 500's up until 1992 had the one piece chaincase brake assembly without a drain plug or a dipstick. All Indy 500's 1993+ adopted the later style chaincase with the caliper able to be removed from the top of the chaincase, a drain plug, and a dipstick. I just assumed all Polaris sleds changed over at the same time. My 1996 Indy 500 has the new style.
