I have had the tank running for a month. 75 gallon with 2 filters that both run 300gph. I have had 3 pictus cats die in the last day and the other one doesnt look good. The mollies and guppies look good.
The water parameters are:
ph=7.6
Nitrite=0
Ammonia=1.5-2.0ppm
Nitrate=0
Temp=78F

I did a 15% water change on Sunday. The only chemicals that I have added to the tank is Prime.

Do I need to do another water change to get the ammonia down? Add Prime? Stress Coat?

Im confused.

Ammonia is still high and is most likely causing the poisoning of your cats.
If the tank is cycled properly, ammonia will drop, nitrites will rise and drop again.
And finally you will get a nitrate reading, when ammonia and nitrites are 0.
Your tank is not fully cycled yet, imo.
A month may be a lil' short for the complete cycle.
Cats are more fragile than mollies and guppys and will more easily die from toxins.
Those cats can stand a lot less ammonia...

IMO, no, not just yet.
The cycling proces will need the ammonia to supply food for the nitrification bacteria and the nitrite levels to rise.
As long as the ammonia testresult don't rocket through the roof just hang in there.

I would say do a 30% water change and add prime at twice the recommended amount ie to cover 150g to 200g. with a PH of 7.6 the ammonia of 2.0mg/l is fairly toxic. if the ammonia level was 0.2mg/l then I would say you would be ok to just add a little prime. adding twice the amount of prime is fine, as long as your temp isn't above 30c.

also adding the prime will help break down the amonia and cycle the tank quicker.

No problem Noddy, not often you miss anything. probably the 2.0 and 0.2 you where spot on with the rest. I think the toxic ammonia affected the other fish too, and being more sensitive couldn't cope.
