The shims come in pairs and include new center bolts.
The rear brakelines come in three lengths: 18", 22", and 24". We've always sent out the 22" lines (RE1513) for the rear. Front lines are 20", 22", or 28", and we usually have the 22" (RE1550) sent out. The RE1560 front/rear XJ brakeline kit comes with the 18" rear line and the 22" front lines, which would be fine for your lift.
I don't see an SYE in your list, so there'd be no need for shims.
