You can change the rear brake pads on a lexus GS3000 by loosening the lug nuts slightly for the wheels, raise and support the vehicle safely, remove the wheels.
The PCV valve is located on the passenger side rear valve cover. Simply pull it out then pinch the clamp to release the valve. I would recommend replacing the PCV valve grommet while you're in there, they get hard and brittle and can break into pieces that fall inside the engine.
