Transistor biasing is done for stability at operating point of the circuit. It stops thermal runaway and therefore avoids damaging the transistor.

When you say torn traces do you mean that they are no longer conducting properly? If so rerouting the trace is possibly an option - could be quite tricky though.

Yes if the transformer goes bad it could cause damage to the circuit if it does not have an internal fuse. If it has a fuse it should just trip the fuse.
