As per Robin's alignment page on pcar.com, it looks like your front is a bit out of spec on the caster (he says 5°20' + 15', whereas you've got 5°40' and 5°50'), and the rear camber looks out of spec as well (he says at most extreme RS specs -1°20'±10', where as you've got -1°60' & -1°70'). It looks like that would explain the fast wear on the rear at least. I'm sure someone smarter than me will chime in on the rest.

I had a comment from a friend just recently that I'm running too much neg. camber in the rear and that the inside edges will suffer for it. The place where I got my last alignment advised I bring the car back at 3k miles to check the wear patterns for any issues, and I'm at that point now, so I will go in and report back here if I find anything pertinent.
Sorry if my explanation or questions are dumb, just trying to help.
Here are my alignment specs:
Front Left:
Camber -1.44*
Caster 5.53*
Toe 1.8mm
Front Right:
Camber -1.43*
Caster 5.52*
Toe 1.8mm
Rear Left:
Camber -1.71*
Toe 1.9mm
Rear Right:
Camber -1.71*
Toe 1.9mm
