CS finally got back to me after I put in a ticket over a week ago.
I lost 6 command ranks, 1 KOTET story chapter progress, ~100 solo ranked points and a NiM kill cheevo in the rollback. My CM purchases and GTN sales/purchases were unaffected.
They awarded me 6 command crates, 5 CXP boosts, 750cc and an extra 3 days' worth of sub time as compensation.
Although my command rank did not get bumped up along with the award of the 6 crates, and I miss the extra 100 solo ranked rating, I'm happy that they're doing something for the poor affected souls instead of just keeping mum.
On another positive note, the initial crates I opened which got rolled back contained junk and duplicate items, while the replacement crates from CS contained 2 set bonus pieces
