Question about axial precessions:

Earth's axial precession is rather well documented. I figured it's value is about -1.39 deg/cy. Does anybody know a source where I can find values of other planets and maybe even moons?

More generally:
Should the direction of (axial) precession not be determined by the rotation direction only (prograde, retrograde)? At least from conservation of angular momentum I would guess so. But if yes, rotation direction w.r.t. what? Ecliptic, Orbit, Invariable plane, ...?

Anybody any idea?

thanks,
Mike
