Two of what next..?

Also Prot Pallys do very well, level 78 should have very decent gear for boosting pre 60.

As for what to bring up...
2 Pallys would be good, you already have one on the main account so you would end up with 3 of them, same with Rogues and Mages.
I really enjoyed my mages and look forward to playing them again when I finish leveling my dungeon team. So I would say ensure you get at the least the Pallys and mages to 60 during your RAF time.

I'm actually using pally with shamans, it's doing extremely fine in every instance shamans can get up using random dungeon tool. I also boosted them as lowbies with SFK -> SM -> ZF -> Strat ->

Mages sound good also, maybe frost/fire combo... *ponder*

Im taking my mages arcane for PvP for maximum instant casts from Arcane Barrage and PoM. also I will be able to get instant invis, +50% crit, 5x slow and sometimes really hasted arcane misslies

But thats just my personal preference. Im sure all mages can have real fun. I can imagine a group of Frost mages all using slowing blizzard with the chance to freeze on slow effects on large amounts of melee.
5x Living Bombs and/or dragons breath from fire mages.

Ahh the possibilities are endless.
