3 times per week is sufficient
I'd wait a few days before trying, typically when they molt its a 1-2 week process and they close themselves in for awhile, this one obviously couldn't close up which was the major concern so i'd leave room+lights as dark as possible for first few days and see how it is. They need to be able to create large U-shaped completely dark burrows so if you have decor rocks with holes you may want to plug them as much as possible and give it rubble to make its burrow entrance doors. When they don't have those conditions they usually die which was the major concern with it molting in the bag, seems like the worst has past and you're in the clear just waiting for it to eat again.
Normally I'd say leave the molt for it to eat but I see visible shell rot on it which you probably don't want to keep old infected shell in.
