With the parking brake set and the engine running, use an engine stethoscope
or a screwdriver with a long shank up against the alternator case to listen
to the sounds coming from the alternator, then turn on the light and rear
defogger and listen again to see if the sound gets louder. Also check to
see if the sound is coming from the headlight relay.
I think the drivability problem is unrelated to the sound. How many miles
are on the clutch and what kind of driving do you typically do, i.e., start
on hills, stop-and-go, frequently downshift, etc.? You could have a worn
clutch or a problem with the clutch master cylinder.
