I have some new rotors that have a grey paint or zinc coating to them. This is on a 2001 Silverado. Do I need to sand this off? I'm going to spray some brake cleaner on it. I'm not sure if that is enough.

New rotor help needed

Brake cleaner has always made it run off for me. I believe the idea is the pads wear off what they need to and the rest stays coated to prevent corrosion.
That is what I did just run it
I usually buy coated rotors. It especially helps in the fins where road salt can get them all crumbly (which has to effect the cooling). I always just throw them on and bed the pads. If brake clean makes it run off, it's just a shipping coating. It's usually the uncoated rotors that ship oiled and need to be cleaned off.
I didn't even know it was an option until a couple of years ago when I bought a set for my 97 suburban and I saw the coating.
I like it.

I used brake clean on the rotors and the painted coating did not remove. I installed the rotors and the new pads with the painted coating on. I need to remove one side however and redo my work. I did not adjust the parking brake shoe.
Back in the 90’s I worked at a large Toyota/Lexus Dealership and the Lexus customers were complaining about how they could see rust on the rotors/calipers after it would rain ( more evidently on the larger diameter wheels ).
The fix was to spray it all down with primer ( let dry ) and immediately take the vehicle out for a few high speed hard stops to burn off where the pads made contact - it seemed to work with no issues.
I would think it would be a best practice to remove any oil based protectant before hand so as not to effect the pad surfaces though.

These are not oil based and they are intended for what you described
