If you are interested in quest addons that know what you have done, what you have left to do, and where to find those quests (including things you need to kill to loot items that start quests), you may want to use Wholly (the UI) and Grail (the quest database backend). Currently an effort is underway to improve Grail's database of MoP information and you can participate by questing in MoP beta and submitting your Grail.lua saved variables file. You can download the latest Wholly and Grail from wowinterface.com or curse.com and they both work in the current live WoW as well as MoP beta so you can use them for your current questing needs as well. Thanks for your help.
