ProjectRB speaks the truth.
Sounds to me you might have a few of the following from what you said.
The low speed squeal might be due to a glazed rotor surface.
The high speed vibration could be due to a few things. - Excessive rotor run-out (aka warped rotor) - Pad material build-up on the rotor (happens when you don't let off the brakes after a hard stop)
But given the choices I'd say you have glazed and warped rotors, and they require a resurface. This is more than likely due to an improper bedding procedure which the tech at Infiniti should know how to do, but he may not have the facility to do such a procedure correctly, ie. open road.
