You can run any slick without tire warmers, you just need to make sure you give the tires a couple laps to come into temperature so they're safe to push it on.
Tire warmers will offer no real benefit on street tires, I wouldn't waste your time.
As for using them to reduce heat cycles and prolong tire life there is some truth to that. But it adds up to such a small savings that it may not be worth it.
I rarely use them at a trackday unless I've got a good group of buddies I'm riding with that want to push hard right out of the gate. If I'm racing they're always on as every lap counts.
As for using street tires at a trackday depending on your pace you should be fine. Just do some research on the correct track tire pressures as they will be considerably lower than what you run on the street.
If you've got them already they won't hurt anything by using them regardless of the tire. But I wouldn't run out and spend the money on them if you're just doing trackdays, they really aren't necessary.
