Is this phal salvageable?

[RandomGemini]

So, I got this orchid. To make a long story short, it was gifted to a friend and given to me to "save." I love the spattered looking blooms. I'd like to save it if I can, but I'm not sure how healthy it is, because I haven't seen roots this dry before, some of them look shriveled and feel papery. It looks like it might have some new aerial roots trying to grow though. One of the leaves has a split down the middle and another one has a torn corner. Not sure what I should do about that, if anything. Also, when I lifted it out of the ceramic pot, a couple of gnats flew out.

The other orchids in the house do NOT look this bad so I'm not sure where to begin. I have it separate from the other orchids for now, because my other orchids seem to be doing great and this one... well I'm afraid it has cooties.

So far, I have done nothing. I've left it to sit, but my gut's telling me "Repot! Repot it now!"

Anyway... here's some pictures of the damage. Any advice is helpful.
