No, no kit "requires" any of this but doing so is more of an opportunity cost.
Spend a little extra now, for you a bit more because of fees & such, but save yourself in the long run. Protecting the engine is key when throwing on this much extra power, heat, and more. Investing a few extra grand now to save your engine in the long run is a much better idea than not spending it now and messing up your engine and dropping 4-5x that much to get it fixed.
On the things listed you can sort of pick/choose how you want to do it.
If you upgrade the radiator consider the fans with it because it all comes out and saves you labor and time. For other items compare and contrast price, install labor, etc and see what you want to do.
Oil cooler I will say is a requirement on this car, even bone stock it runs hot.
