microlight was kind enough to send me his optimized .air and .cfg files. I have FS00 so I had the other original MS files (about the only thing 00 is worth).
If you have 00 there some instructions but they are horribly complicated. There is a .doc file at AVSim that's much simpler.
It isn't that hard to fly. With the simplified instructions I got it up to cruise speed (mach 2) and alt (FL500) in about 200 miles, turned around and landed successfully the first time. I just completed a flight from Miami to San Francisco in 2:15, and landed an hour before I took off!
The MS panel needs some work (don't they all?) but a few mods took care of that. There is an alternative that microlight likes better (look in the library) or I'll send you my mods of the MS panel(for FS02 - better GPS, throttle and radio stack and added TCAS).
Edited to correct typo and time zone calculation.
