Your gear is fine for heroic HoR - you're at about the same gear level as my
Paladin alt, who's been able to heal it a few times (the last time actually felt kinda ... easy, though I had a good group).

Cooldown management and mana management will be the tricky part. If you overgear the place, you can usually get out of tough situations by turning on the HL firehose, but at level it's not so simple.
At his gear level you may have no choice BUT to blast HL indiscriminately if the situation requires it. Luckily, you can usually melee the last mob with SoW + Divine Plea, which will refund a lot of that mana. I know when I heal, I've seen a majority of my healing come from HL, even though I cast FoL a lot more.
I think a lot of healing the instance depends on knowing what the mobs do. Assuming your tank is good at picking up mobs and your DPS are focus firing (I know - I dream, I dream), there are only a few things that are dangerous, and most of them are dangerous only to the tank - rogue stun, rogue poison (the single stack, not the three stack), and the combo of curse + magic damage, especially combine with #1 and #2. The only thing that's really dangerous to the group is Flamestrike, which is mitigated if you spread out after the pull.
I guess my question to the OP is:
How is the group dying? Are
you taking aggro on the pull? Are DPS pulling off of the tank before he's corralled all of the mobs? Is the tank going down once he has the mobs on him?
