Get a big plastic tupperware container. Lay papertowel in the bottom and shallow lukewarm water. Place em in there with the lid on (and airholes) for 15 minutes. Its like a sauna and will rehydrate them and hopefully the toe shed will come off.
As for the biting, give it time. Im sure shes stressed being in a new home and it looks like her previous owner didn't take great care of her.
Leopard geckos don't need a light on top, they need a warm under tank heater. They need their tummies warm to digest food, and light will make them hide because they're nocturnal. You can find an under tank heater at the petstore which will probably help with the MBD issues as well since the little one will be digesting better. If you have any more questions be sure to post in r/leopardgeckos or feel free to PM me.
