Several questions about Saitek x52

I got a Saitek x52 for christmas (which is an absolutley amazing controller) but i am not sure about how to program certain commands with the sst profiling software that came with it. So i have a few questions to ask:
1. How can I set the slider control on the throttle to do mixture control in fs 2004?
2. If the pinkie switch is set as a shift button then do you hold that then press another button for more commands?
3.Like 1 but how can i programme my rotary control on my throttle to do rudder trim?
Thanks for your time any help would be very much appreciated.
