A mountain of data exists but if you are still puzzled after doing a bit of research come back with some specific questions and give more information about where you are in the USA and where you are trying to trying to grow the plant.

I live in Santa Barbara, CA. It's pretty humid since we're close to the beach, but the weather is all over the place -- one day it will be very sunny and the next, very cloudy. I learned that the blackened root tips were from toxicity... my living room smells like cigarettes because one of my roommate smokes and deposits her butts in our trashcan.

I do not believe that the blackened root tips are caused by Tobacco Smoke. Santa Barbara might be orchid heaven but Phalaenopsis need warmth but not strong sunlight, so a bright window after you repot it as Jane suggest would be good.

You might have gone from one extreme to the other with the wetness. I think the black tips were caused by the packed spag.

Anyway try and find that nice warm spot as described in most notes and see how you go. Plant is in not too bad a condition.

Santa Barbara is Cymbidium Orchid Heaven.

Temps for Phalaenopsis not below 60F, not above 90F.

It hasn't been too warm lately... the wind has been really cold even though humidity has been up. The weather has been all over the place

Right now you just want to keep those roots and the base of the plant as humid as possible without being soggy. Though I typically advise bark for phals, I'd start with loosely packed moss for this plant, and mist it daily. Eventually it will grow a new robust root system, and then you can put it in bark. It will take a long time, but if you keep it hydrated, which will be its biggest challenge right now, it will come back. Don't be surprised if it sheds a leaf.

Best of luck!

I just ordered a bundle of sphagnum moss to come in. It's in bark now but it loses so much moisture so easily.

I would put it into a clear glass or vase with 1/4 root tip wet. Leave ut stay there for awhile until the root regrown. Make sure u chage water oftenly when it abit cloudy if u doing this way. Good luck!

but don't peals hate standing water?

Your plant will survive if you follow the good advice given above. Don't plant in sphagnum alone. Mix a little sphag with some bark (mostly small bark) and soak the bark and moss first before putting the plant in.

As Arthur said, it needs warmth and bright light. Put it in your brightest window (not direct sun) and leave it alone. Only water when almost dry. It will recover, the plant looks fine and just needs repotting.
