what addon if any will let me know when Art of War comes on my pally? in the middle of battle im not looking in the top right corner of my screen very often.

Scrolling combat text (curse version is out of date, get it here: http://www.wowinterface.com/downloads/info3965-ScrollingCombatText.html)

You'll want to add a new custom event, set to search for an aura gain called "Art of War" and displays "Art of War!" (or something to that effect).

TYVM!
