I would get a plastic storage tub and keep her in that on paper towels. Basic "hospital" environment. Put holes in the tub for some airflow.
82 is a bit cold for digestion, but won't really hurt her. Get a heat pad or a small bit of flexwatt to put under the tub for a hot spot in the low 90s. Use a thermostat or at least a lamp dimmer.
Have you read the caresheet?
Good luck with the poor girl. Some people...
Edit: lol, beat to it.
