I'm not convinced that that set is BiS for WAR (not that there's really much difference at our current stat levels). Personally, I've been going for Critical Hit (http://ffxiv.ariyala.com/12ZFZ).

As for Skill Speed, 2.44 GCD is serviceable, but I think 2.4-2.39 GCD is best. I wouldn't go any lower than that, however.
