MFS 2004 Beginner

Hello all. Am new to the software as have developed an interest in obtaining my PPL eventually. My question to whomever can assist is: Can someone provide me with the best settings for MFS 2004 that would make it easiest to learn the program? Am running it on a P4 2.8 Ghz with 2GB DDR RAM. Additional hardware is the Saitek Yolk, Throttle, and Rudder Pedals. Am particularly interested in the sensitivities section as am having problems using the Yolk to control the flight of the Cessna 172SP (Flight lessons). Thanks to all who respond.
