Saitek x55 buttons and switches configuration

Hello everyone

 

A few days ago I bought Saitek x55 Hotas. Now I use my flying Saitek x55 (Joystick+throttle), CH Rudder Pedals and Saitek Pro Flight Throttle Quadrant.

 

I would like to ask how to set up this gear? I fly mainly IFR (A320 and B737). Should I completely configure this set via FSUIPC (axes, buttons, switches)? Or another option would be better?

 

Here is my conception

-CH rudders - Rudder and brakes,

-x55 Joystick - do not have to explain

-x55 throttles - throttles - a question here - is it possible to set up reverse thrust?

-Pro Flight throttles - left lever flaps, the middle - spoiles, the right landing gear?

 

Do you have maybe some ideas on how you can develop the buttons on the x55 throttle and joystick? 

 

Thank you for any suggestions and help
