Good morning,
Well let me start by saying that changing the calipers is not a normal thing to do on a car unless they are damaged or severely worn out, leaking or seized up. Given the age and mileage on your vehicle I would be highly surprised that you needed to. I have a 2003 with almost 300,000 miles on it and I am still running on the original calipers.
Changing the rotors is done as needed. The only time you need to change them is when they are worn out, damaged or warped. These can be damaged by neglecting to service your brakes in a timely manner where the pads are gone and make metal to metal contact, scoring up the rotor and making lots of bad grinding noises. Sometimes they overheat and can warp which causes your brake pedal to pulsate when you brake. If your brakes do either of those two things then you should replace them. If not, then save your money and just do the pads but have the rotors inspected to see if they still have enough thickness left in them.
Always do brake service in pairs, left and right. Whatever you do to the left side, you should also do on the right side. I have found that front brakes require service more frequently than rear brakes. This is because the car makers put a "proportioning valve" in the brake system that controls the "bias" of the brakes. The front brakes work harder than the rears because when you step on the brakes, the weight of the car shifts forward and gives front wheels more traction, so to take advantage of this, the valve send more pressure power to the front brakes.
There is no reason to service both the front and rear brakes every time but, it is a good idea to inspect the rears each time you are going to service the brakes.
Are you having a specific problem with your brakes or are you just asking for general information?
Jon
