I am only doing instances from 30 to 80 (now level 77)

So i have missed just about ALL the quests in Outlands and NR. But tell me are there any necessities to get from the quests to make heroics at 80 easier.
I did a few of the dailies at venture co. and got my self the lava burst totem and working on the trinket now.

But for me and the other mulitboxers that have missed a few things here and there, inorder to be ready for 80 heroics what are the necessities like random trinkets from quests, etc.

Thanks for you input.
