I'm sure everyone will have their own methods, but this is what I'm planning: 1) Making sure I have a day clear of raiding or other activities since it'll probably be very time consuming. 2) Using alts parked in different zones to make it faster to get from point to point (I already have 1 in Kalimdor, 1 in EK, 1 in NR - also I have a lot of teleport items to use as well). 3) Making sure all the alts are well stocked with pet bandages.
I plan on going in reverse order, that is, highest level to lowest. That way I get the harder stuff out of the way before I burn out, then I can be lazy with the easier ones.
I already have teams set up for all the Panda level trainers since I've been doing those daily. Anything under that I can probably power through with my self healing, pet farming team - Wild Crimson Hatchling, Leopard Tree Frog and a boosted pet.
