Unusually large number of white spots?

My tank has Ich (for sure) and I have lost 5 tetras from it (RIP comrades). The remaining trooper is a Dalmatian Molly (Moo) and he was docile a couple days ago. I have the temperature at 81 F, 25-30% water changes before every treatment (Using Aquarium Products QuICK Cure (top rated)), aquarium salt, feeding a varied diet. He swims around fine now and always comes to the front of the tank for food, I have been vacuuming the gravel during water changes and water parameters (using API Freshwater Master Test Kit) are spot on before every water change. I add a little Stress Coat after the water change but before the treatment and leave the light off (with the blinds in the room open to let minimal light in) so he isn't so stressed.

Here is a picture of him. Why is there so many spots? Is that usual (it doesn't seem like it to me)? Is there anything else I can do to help him out until it's all gone?

Thanks guys.
P.S. I know it's not the best picture, but it's difficult to find a time when he is not swimming so much. He acts like he's never swam before, ha.

Anything you recommend I do other than continue the treatment above?

I also have an air pump in there to help him.

I have removed the carbon filter, per instructions request, and I have begun to breach the 81-82 F mark and venture to around 85 F slowly.

What are signs of heat stress and low oxygen?

The only thing that is concerning me right now, as far as the looks of the poor fellow, is the fact that he is swimming A LOT right now, more than he usually has.

I'll be honest, he's in a 10 gallon right now (I have a 20g and a 55g I got used, 20g is set up and waiting for him to move in once he is better) and I got into fishkeeping with a new tank and a few fish. Needless to say, he's been with us through the whole cycling process too (that was fun changing the water like a mad man to keep them comfortable). Should have done research before buying fish! Anyways it's cycled now and all is well except this Ich deal; the Ich came along immediately after the finished cycle. Do you think it's too much stress on the guy or are Mollies pretty resilient?

ALSO, would any recommend using QuICK Cure and the salt treatment? Too much stress?

Thanks Slappy. I feel a little better. I haven't been doing table salt. I have just been adding maybe a teaspoon of Aquarium Salt (API brand) periodically and with water changes to replace what I took out. Not sure what level the salt is at, but it's not ocean-salty that's for sure.

He hasn't been gasping or near the surface, he used to before I got the air pump a couple weeks back. The only thing that's different about him is his rapid swimming and especially when anyone comes near the front of the tank, he'll act like a puppy and just swim into the glass of the tank and wiggle like he's a 70's dance pro. He never was that excited before.

I have been adding slowly. My light is off and my fish is sleeping a lot. Is it okay that he sleeps through the night and mostly the whole day?
I do turn the light on just to get him to come out so I can get him to eat a little.
