I have been really interested in multiboxing for a while. Last year I used a wireless keyboard to dualbox two hunters up to level 19 for some WSG fun. I am now ready to take the plunge and 5 box it up. I have my hardware/software setup already sorted out, I just need some tips since my situation is rather unique.

Right now I have three high level characters on three separate accounts. I have two 70 dwarf priests and a 68 Draenei Shaman. I am going to start 2 more accounts so I can have my own instance team. I was thinking about making a protection paladin for my tank. What should I make for the 5th character in my setup? I was thinking maybe another shaman and specing them restoration. Any other suggestions? I was thinking a warlock or a mage.

Also, since three of my characters will be 70 by the end of the weekend, how should I boost the other 2 efficiently? How should I link the accounts? All suggestions are greatly appreciated.
