Mobsters don't stand around like zombies waiting to be killed.
They do if the Gawdfather puts a hit out on them.

I really, really think Healing Word can only be used during an encounter, like it says in the power description. You can't use it while "resting".
So what? My Rogue will take that all day.... he only has 7 surges and gets through them very quickly!! Last night when we were playing, we entered a major evil temple with my Rogue 2 character on 5 hps and no surges.+1d6 on a healing surge. So what?
Your cleric is wrong. Encounters count as "fights" or "skill challenges" or something else applicable as decided by the DM, but generally just those two things. You can't sit there idly and keep adding the extra healing from Healing Surges. Although if you end up waiting 6 hours you get all surges back anyway. I'm not quite sure what angle your player is taking, sounds like he's trying to argue for a loophole that doesn't exist.
