I use...
Recipebook (Shows you how many items you can make using things in your bank & vendor instead of just bags)
Titan Panel (all standard expect CritLine and Factions)
Call of Elements (for shaman totems)
Meta Map (World maps and show un-explored)
Atlas enhanced (for Instance maps and loot)
Monkey Quest (Quest UI)
ADSpace (no more spending stupid amount of money on recipes off the AH when they are available off vendors)
EuipCompare (Shows what you are wearing compared to thing you are hovering over all the time, instead of just in AH & Vendor)
CTMods
