I will like to know if I can just leave the Standback with no tune and install the AP and use the Standback to change boost settings only?

I don't believe you can do that. I think that once you program the ECU with the AP that it will be locked unless you use the same AP to change parameters. If that is correct, the Standback will not recognize the ECU once you have programmed it with the AP.
Sounds kind of scary. I would hate to see you corrupt your ECU and have to replace it.
EDIT: You should use AccessTuner RACE with the Cobb AP if you want to customize boost levels.
