I am cooking a whole turkey breast and boneless turkey thighs. Not sure how long to cook each of those?

The thighs will go quicker than the breast, since it's on a bone—so cook them in separate dishes and just keep checking the internal temperature of them both. A good starting place (but it's not hard and fast!) is that at 500° F, it should take 10 minutes per pound of turkey.
