The shoes are a full single shoe under the rotor. You need to take the rotor off the axle to see it.
Ok, turn the star wheel to reduce teh clearance. Then install the rotors and adjust the nut.
how much do I adjust or turn the star wheel to expand the space?
Until there is next to no space between the shoe and the rotor. The less the space, the less travel in the park brake pedal.
While you have the rotor off, check the lining thickness. It needs to be about the thickness of a dime in the thinnest spot or you will not get enough travel to properly adjust the brake.
ok, do I back out the nut on the equalizer backwards towards the end of the stem or towards the the front cable?
