Uknown Thru Cal. between waveguide and coaxial ports

I have to use the Unknown thru calibration because I have to measure one DUT with one port TNC and the other port WR-90.

I have some questions:

1-Before calibration I have to set System Z0 as 50 (coaxial) or 1 (waveguide)?.
2-Before calibration I have to set Electrical Delay as Coaxial or as Wavegude?.

3-This calibration is valid to measure S21 or it is also valid to measure return losses of both ports?

4-The nominal adapter delay and nominal phase offset calculated are good values? or I must to know them?. In case I must to Know this values, how can I get them if I know the phisical length of the unknown thru used?

Thank you very much for your answers.
