I guess I'll chime in with my 2 copper/cents/rupees. I'm using a Prot Warrior: http://www.wowarmory.com/character-s...oon&n=Valdenar
If I had a mage, I'd use him, but alas, I have to use what I've got.
And what I've got is 2 AoE shields, (Sporeggar and the Force Reactive Disk, both with spikes), the Naglering, Chained Essence of Eranikus, and the Electromagnetic Gigaflux Reactivator (Free thorns buff kinda). When used properly, I can decimate the entire pirate boat in Dead Mines without even attacking anything...If BC hadn't come out when it did, I might have got my Thunderfury (Essence and 1st binding still sit in my bank), and I'd be even more of a terror, but oh well, maybe I can get it for looks later.

As for the micro management in moving the characters, I do one of two things (I'm boosting a single Healadin):
-Move in chunks.
Dead Mines, I just clear up to each door, bringing all the mobs back to my lowbie, then run them up to the door and hide the Paladin in a corner (damn patrols). Works good, just have to swing back a little sometimes to make sure to get those nasty patrols...
Stockades is easier still, I clear the first hall, then move my guy into the second room on the right, the far NE corner. From there I can get exp from the end of the East hall. Clear that one, move character into hallway just a little ways down as I make my way down that hall (doesn't need to be far). I can clear all of Stockades in just a matter of seconds over 10 minutes, so it's not too bad.

-Bring a friend! When I was boosting Dead Mines I usually got some random newbie asking me to take them, so I do. You can easily put them on auto-follow, and if you have all the possible drops anyways, I just have them pick up all the loot (saves a TON of time). Plus since I'm just dual-boxing, it gives me a slight group bonus, which is nice. You could even charge them, especially if it's a twink gonna-be.
