Yes, they are different front and rear.

Lemans was suggesting the Axxis Deluxe pads.

Presume you know to replace the sensor (the one that caused the light to come on). It is a single-use switch, disposable. One on the front axle, one on the rear.

How long since the brake fluid was replaced? It is scheduled for every 24 months. Also check rotor condition. They aren't usually turned on a lathe, but simply replaced, if they are at the minimum thickness or if the surface finish is not great.
