This pretty much, only think I would add is saving Swiftcast for Holy is also an alternative to using it for Medica II (Just a matter of what will help you the most in the heat of the moment), If you notice the tank's CDs are about to wear off and know its going to be hard to heal the AoE stun gives you a chances to get a few spells off to top him off, very helpful if you use it right. While I will never say do this without CS up (go go healer deeps!) if you are just having a hard time keeping up don't even worry about CS just use it for the AoE stun.
