..One thing she could do to clean up the alternator question would be to get the identification numbers off of the alternator and see for herself if it matches up with her car.  She could do it herself online or call one of the parts stores.

Yes, or obtain alternator ID off receipt.  Mechanic gave that to her with his bill, right?

Oreilly's will test your alternator for free, btw.  

Quite unlikely this component is responsible for the car running poorly.
