If its a dark color and you intend on keeping the car for a long time, get the bra put on. Otherwise, it's not worth it. I would not worry about getting it reprinted unless the chips are really bad. Also, typically every one just covers the hood and front bumper. My installer advised to put the rocker panel pieces on. I should have listened as I can see over time how the rocks kicking from the tires are chirping the paint in that area.
Congrats on your purchase.
