Gratz on you first car.

You should get at least 30k miles out of your brake pads with normal usage. Cost isn't much, under $100 I would image. Calipers and Rotors are another story, if you need to replace those under 100K miles you are driving the vehicle pretty hard.

The salesman should have activated Onstar for you at the dealer, either way you can do it by pushing the button and talking to them through your car speakers.

Go to the Chevy dealer and speak to the parts department, they can order you the ground effects...
