I guess the thing that concerns me regarding surge damage comes from a customer we used to have (a local municipality); every time there'd be a lightning storm, we'd lose connectivity to a handful of our firewalls. sometimes it would be catastrophic failure of the device, sometimes it would be just the ethernet port connected to the cable modem.

I've had that. But the real damage was when there was a voltage spike, either on the mains or via the overhead phone lines. When that happens surge protectors can be useless. They aren't designed for spikes that rapid and vicious. They are just too slow to respond. I had a PC's motherboard, a fax machine and printer wiped out. No Ethernet connection involved.

I ask because the bedrooms where i'm going to connect these guys are on different breakers than the breaker supplying my network closet. it's a guaranteed two breaker hop between any two powerline adapters. unless there's something different about the main breaker and maybe the higher voltage coming off of the street?

Powerline relies on the plugs' ability to talk to one another over the mains circuit. This can leave them open to interference or to blockages when there is something there that tries to manage the power.

My experience is that plugs have a hard time communicating through fuse boxes. I have a separate building that shares the same mains service, but with boxes for two separate buildings. I don't have problems with plugs within each building. These circuits are on separate upstairs and downstairs fused loops within the building. 

The only way to see if it will work is by testing your circumstances.
