Her gums look a tad pale in the pictures (could be due to RI / malnutrition / lighting of the pic), but without the bubbles and such and a ton of mucous, the wheezing could also be the messed up nose. Looks almost like the majority of that nostril has been ruined, so breathing won't ever be normal. If it is from a bite then the bite itself could be infected as well. Antibiotics may be the only course of action for that.

As for temps, 95-98 is too high in my opinion. I'd have a hot spot on a regulated thermostat no higher than 92 and bump the cold side up to no higher than 85-87. You want to help her thermoregulate without cooking her - too high of a temp without being able to cool off will stress her just as much as too low of a temp. Bumping humidity to 70% would also help.

Trying to get her to eat, keeping stress at a minimum, and proper temps, are about all you can do on your own...I know things are tight, but sometimes antibiotics are the only fix. It does not look too infected yet, so she may have already healed the majority of the mouth / nose wound
