Not much you can really do.
From experience with my own rubber plant:
1. Do not remove the leaves yourself. Let them drop off
2 Do not cut the stem of the plant
Just leave it all, and it will recover. Removing the leaves will expose the internals of the bark. The new shoots actually come out just above where the leaves are attached to the stem, so removing the leaves will cause the new shoots to die.
Mine was severely frostbitten, but came back spectacularly in about 3 months.
