Pally + Mage, and Shaman + Priest Dual-Box Outlands Leveling

Hi guys, I've obtained 6 level 60s from 3-boxing Shamans from 1-60 and RAF.
Although I used the 3x shamans purely just to get the free characters (pally, priest and mage).

Now I'm hoping to dual box my Pally + Mage to 70 then my Shaman + Priest to 70.

As for Pally + Mage, should I go protection and frost for good AOE? Also with this combo would questing or AOEing be faster in outlands?
This is my first priority since once I get them geared at 70 I can boost any class to 60 under a day :)

As for Shaman + Priest, this will come later when I get my pally and mage up to 70. I'm planning to use my Shaman as my main, since its tougher. I suppose I'd go enhance for that purpose?

Also if you guys have any general tips about leveling in outlands please feel free to share :)

Thanks in advance.

Bump, anyone?

I am new to Keyclone, and i am waiting on a reply to get it up and running, so i will atleast shoot in the dark to try and help you out, as i have leveled a lot of characters without multi-boxing.
FOR LEVELING
Mages, go frost
Paladins, ret (prot isnt TERRIBLE if you have friends along, which you will, so this is also viable.)
Shamans, ENHANCEMENT lawl ezmode leveling. leave the food and water at home.
Priest, shadow.

[edit] Ack. Just noticed you only have two chars. No idea. It's been so long since I haven't 5-boxed I haven't a clue how just two chars would work.
