I actually use TidyPlates to track combo points, bleeds, DoTs on mobs. In the past, I've set up my PowerAruas (now WeakAuras) to show me my combo points and to flash my finish moves icons when I reach 5 combo points (in case there are too many mobs to pay attention to TidyPlates combo points).

speaks very highly of RoguePowerBars for tracking all of his bleeds/debuffs across all of his toons... you could check that out, too.
