personally, here is what i did when my BP got hurt like a year and a half ago...
he got stuck and got his belly scales tore up.
the vet gave me shots to give him, and i cleaned him with watered down betadine.
i was told to put him in a rubbermaid, with clean paper towels, and a water dish.
i kept him warm with a human heat pad... but i had it regulated.
and i took temps constantly.
because his scales were damaged, i had to keep him super clean so he wouldnt get scale rot. he never did - so i'd suggest keeping her on paper toweling in a rubbermaid with clean water.
if she dumps the water, clean it out, put fresh paper in, and re-fill her dish.
keep the paper dry.
as for cleaning the tank... take everything out, and use a reptile safe cleaner. i would keep her in a tub for now, because it is easier to keep clean.
course thats my opinion.
