Until last update, recast capped at 50%, it has been raised by an unspecified amount. Cast time had the cap raised a while back, but I'm not sure when. I believe the current cast time reduction cap is somewhere in the neighborhood of 80-85% (think other caps with a similar number).

Cast time gear is hard to macro in as you get more, just because your cures go off astoundingly fast, which means you either gimp your cures or get fast cures, generally. Personally, I think a balance between cure potency, cast time, and recast time has to be reached to be the most effective White Mage you can be, and in some situations you might want to prioritize some over others.
