I chose to go down the STA and INT lines. In STA, I went all the way and got Serenity, and maxed out my crit heals. In INT, I went all the way to Stormvision, put 5 points in that, and maxed out the spell crits.
I'm pretty happy with my selections. 
Edit: I should mention that I am a mostly raiding Fury, and when I do instances, I'm usually the second healer. The crit heals help a lot in raiding, and the crit nukes and extra disruption help add a little bit of DPS when I'm grouping.
