I am trying to fine tune the controller and APs to have better wifi at our schools. Should I change the "RF Domain" option per school building? Should each building have its own RF Domain name? So it will only manage that specific schools APs? We have about 50 different buildings, all on different subnets. All the APs with the RF Domain name, "MyDomaintest" will all be in their own little group, seperate from the rest of the APs?

That name gets periodically advertised out by the radio, other ap's in the same domain/area can use that for power tuning and dynamic channel selection. There should be no issues creating RF group names by buildings. Like you mentioned, they would participate in their own groups based on that rf domain name.
