Del, glad you built the kit, and thak you for moving the discussion here. I hope other member will benefit from your questions.

The Slow Stick has 0 downthrust and the stab is set at 0 incidence, but the wing has a positive AoA (front wing support is higher than the rear). The wing also has a single-surface airfoil--this increases the efective AoA further, but I don't know how much because I don't know the airfoil's polar.

The 0/x/0 setup on the Slow Stick is related more to the manufacturing process and ease of assembly than aerodynamics. Let your fixed-wing experience be your guide in choosing angles on your scratch-built model, and then multiply them by a factor of 1.5 as a starting point. The reason is the slower airspeed and higher drag of a gyro compared to an airplane.
