Welcome I'm Chris aka Moose
You have a task ahead of you. Getting rear rotors off this model are a pain. If replacing the brake pads, rotor removal is not needed. If your replacing the rotors then you do not have to be gentle. If the rotor is loose and wobbling then its the parking brake shoes inside that stuck out and holding the rotor on. If its not loose then soak the studs with penetrating oil, then use a large hammer to strike the rotor between the studs to help break the rust bond. Then use a piece of wood against the rotor back side where the caliper was. Hit this piece of wood to drive the rotor off. Forewarning, I have had them stick to the point I had to cut them off with a torch and install a new hub and bearing.
