If you can afford it, forget about the joystick, add some realism and go for something like the CH FS Yoke and Rudder pedals.
Ok, this combination will set you back around £200 (ish), but will help a great deal with flying (albeit in an MS world); you'll certainly learn hand, eye and foot coordination
If your budget doesn't stretch to that much, go for something like the Saitek X45/X52 - seperate throttle/stick controllers and stacks of buttons (if you like that kind of thing).
Hope this helps.
