Ewww, don't like the sound of that temp and the laboured breathing. It does sound like pneumonia, in which case she needs antibiotics, Tetroxy LA is good. But I'd speak to the vet to be honest, though if she were mine and I couldn't get to a vet til tomorrow, I'd give her the Tetroxy anyway.
And she needs food. By now I think I'd be drenching her with a mixture of mainly Readybrek with molasses/syrup added and live yoghurt/rumen starter too. Make it runny. Basically make up the runny Readybrek (with water) and then add a couple of tablespoons of live yoghurt and a couple of tablespoons of syrup to about a litre (it's not an exact science). Put it in something like a washing up liquid bottle. If you can enlarge the hole and add a piece of flexible tubing so much the better, but it will work with just the bottle without the lid - just messier.
Hold her head slightly up, (easiest to do it from behind, standing astride her, facing her head end), get the bottle into the gap between her front and back teeth, make sure you stop every mouthful so she can swallow, the last thing you need is her inhaling it.
