For later instances it's quite hard for a healer class to reach the health required to survive most attacks done by Tier 6 raid bosses. I'd say stamina is worth much more than just 3/10. The first boss in BT required the raid to have a minimum of 10k buffed health. The more the better.

If it's a pally healer you should get Intellect to shield for more mana for heals, because if it's pally healer, plate should give you more than 10k by BT.
There is really no reason for healers to have stamina over intellect for a shield in PvE. If you are that starved for health, grind some honor for PvP gear.
