I suspect not. I don't have specs for any of these enhanced joysticks,
but I'd be very surprised if they are all compatible with each other. If
you can find specs for a Sidewinder, though, it shouldn't be too hard to
add support for it...

This happens. How much depends on the quality of your joystick: I have a
really cheap one that wobbles almost 5% of the total range without me
even touching it! Allegro has some damping code that ignores very small
movements, and provides a 'dead zone' a bit to either side of the centre
position, but you are still likely to get some noise in the input...
