Hi And Welcome,
Adding supers shouldn't have any impact on the brood area.
Whether to let the bees have the honey is completely dependant on the strenth of the hive.
if you have a strong hive Adding honey supers and taking that honey should not be a problem. I almost never remove the honey frames from a brood box because the bees use those honey frames to help regulate the temprature of the hive.
Currently in Charlotte, NC airport changing planes to Boston
