First of all, if ur raid leaders are wanting ur crit between 600-700 and surge between 300-400 then they should not b leading any raid. Do not listen to ur raid leader. In ur current gear i think u can probably run through sm ec as long as the other dps r alittle more geared. Doing that should net u a few more rakata pieces.
Now as far as gearing ur toon from there, this is bis for madness post 1.3 http://swtor.askmrrobot.com/character/86318b2a-febc-40d0-97bc-00f49f95ee45. You should spend the BH comms on tryng to get pieces that r bis. Until u get the campaign armoring just pull mods and enhancements out of that BH gear and stick it in ur rakata if u still want the set bonuses.
Oh, and as far as augments go ALWAYS uses Resolve 22!!!
