Eric,
As for the L1 route preference, that's what I don't understand. If R1/R2 are getting each other's loopbacks through L2 with a preference of 18, but then I swap the L1/L2 preferences so that L2 now has a pref of 15, why would the L1 route always get preferred?
IS-IS always prefers routes reachable via L1 over those reachable via L2, and in this case the IS-IS route selection will only ever export the L1 version of the route to the main junos kernel, and _after_ the IS-IS decision (use L1 over L2) was made junos will apply the global route preference mapping, then put the IS-IS route into it's routing tables.
