Tomorrow when you check on him, if he did indeed have a bad shed, you can soak him in tepid water, not warmer than 93-94* in a caonatiner with a lid, leave him in for about 20 minutes, then let him slither through a damp wash cloth to remove any stuck shed on him. If he has retained eye caps, just leave them, they should come off with the next shed.
I would definitely loose the lamp, it just sucks up all the humidity, so all the misting you have been doing was essentially a wasted effort, because of the lamp.
