I would find another vet. Sounds like this one doesn't know much about guinea pigs.
You're right about feeding unlimited hay. Guinea pigs should never be limited on hay.
Guinea pigs are rarely overweight. Your vet could be wrong. Follow guideline on this page to determine if she's really overweight.

If she is really overweight, to help her lose weight, you can enlarge her cage so she has more space to run around. You can also give her more exercise time out of the cage.
For inexpensive bedding, look into wood pellets and fleece.
