honest repair prices

[Leafgreen]

I would like to get an idea on a fair price for parts and labor from an independent Porsche repair shop for the following for my 2004 Boxster S with 44k miles. Sure would appreciate your feedback

1. "BRAKE WEAR" light came on 3 months ago. The brake pads are still there (not worn away). The repair shop I spoke with said they'd have to look at the rotors too. No sure why. Anyway, what should I expect for the pads alone, and then for the rotors to be replaced?

2. Red light on thermostat temp indicator came on recently.

3. I hear a rattle coming from the front right side undercarriage at low speeds when driving over bumps. That repair shop said it is common for the ball joints to go bad.
