With the Channel Master 7777 preamp, would I need to be concerned about overloading my local channels?
YES, you need to be concerned. Do NOT use that amp. In the event that you find an amp is needed, stick with a medium gain (15-20 dB) amp with high overload tolerance.

I can't pick up RF12 from the ground floor, either indoors or outside,
That suggests either an impaired signal path, stronger localized electrical noise at the lower elevation, or a combination of both.
