Does the presence of the shims affect the distance between the support plates and the rotor? I had calipers (along with pads and rotors) replaced recently and there was a squealing when not applying the brakes. It turned out that one of the support plates (they look more like little spring clips to me) was in contact with the rotor at all times. They eventually ground down the clip a bit but I think it will again contact the rotor when the pad wears. It appears to me that if the shims were present the pad would be closer to the rotor with respect to the clip and thus the clip would never touch. Is the GS300 break system particularly unusual such that this might not be obvious to a generic shop?
