[color=cc9900]I've got the same joystick, Saitek X45. The way I have it set up, I use the throttle as an absolute speed axis, the rudder paddles as a roll axis, the joystick as normal.
From what you say you seem to want to make the two trim wheels do stuff too, like setting control zones so different stuff happens in different positions. If that is the case, then you probably need to roll back to an older version of the profiling software (an iso is available somewhere on the Saitek forums), where you can do that. You ought to be able to do it in newer versions, but for XP compatibility they got rid of some features in interim versions like the drivers I got with mine, so I don't know whether you can do advanced stuff with your current profiler.
EDIT: You mention binding the axis too. Straight off the bat without control zones, sure, that's possible - it's what I've done. Just move the axis when in bind mode in FS2.
EDIT2: That's one crazy pic of the joystick you've found there, I just noticed that all the glowy bits are solid colour instead, except for there being a lens flare on the mode selector. WTF?[/color]
