Rear brake job

I got an oil change and was told that my rear brakes were getting low and needed to be replaced soon. The quote had:
827 Brake Shoes &/or Pads R&R Rear, Both.
New Rear DISC Brake Pad And Rotor Kit.
Brake Fluid Exchange.
Do Hyundai rear brakes have Brake Shoes and DISC Brake Pads and Rotors? If so, does everything need to be replaced?
Does the Brake fluid need to be changed in a 2009 with only 61,000 miles?

My car has 61000 miles.
My car has an automatic transmission.
