No clue about the map stuff you're talking about.
Cooldown type of stuff, ForteXorcist does that and I'm sure there's others that do it as well. No clue if it's the addon you were actually using.

Actionbar stuff.. Not sure which addon but, 2 that could do an arch that I remembered were a Bartender plugin as well as BAB Bars.
