Add-ons are important too. I still use healbot, although I've heard good things about Grid. I got into the habit of casting PoM first on the targetted tank, and binding renew and flash heal to right and left mouse keys. Use Circle of Healing liberally and any time any players other than the tank are taking damage. Pop PoM every time it is up. If you don't have a disc priest in the raid or need more OOMPH as a tank healer, use shield as well.
Dazzit. You should see your numbers double pretty handily.
Took me months to spec BACK into circle of healing.
