Usually. I would recommend doing mirroring on the drives for the
SQL Server, then do a nightly backup/restore or transfer to a
backup server.

Not usually. Unless the POP is multi-homed, there isn't any
advantage of putting a RADIUS server at the POP itself.

It could, but it sounds like more trouble than its worth.
