To get the shed off soak her a couple times and run her through a moist towel and see if that gets off most of it. A couple soaks may be necessary.
For feeding, I would try to get her small rats at that size. See if she will take f/t because IMO rats are a little more fierce than mice, but live will also work fine.
What is the cage like? Do you have digital thermometers and hygrometers to regulate humidity and temperature? How are you heating the cage? What are you using to control the heat? What is the substrate?
Good luck!
