Electronic Ballasts contain circuits that limit electrical noise conducted onto the power line or radiated through the air, otherwise referred to as EMI/RFI. This noise can interfere with electronic devices, and the FCC regulation you specified has a both a somewhat leniant commercial level of compliance and a much stricter residential level of compliance. You just might experience some whackiness with your consumer electronics gear, or you might not. I'd say roll with it and see what happens. The residential level of compliance is strictor so your lights won't disturb your electronics, or more importantly, your neighbors electronics. The FCC assumes commercial buildings are larger, thus the risk of neighbor interference is lessened, thus the standards for commercial buildings were loosened.
for a detailed discussion. I have no idea where to buy a residential rated ballast.
