The 'correct' amount of offset will be whatever it takes to set the front wheel (rim) in the centre of the forks, and the rear rim to be set on the centre line of the frame.

The wheels can be out of line without the offset being wrong.

From the symptoms you have described the underlying problem could be any number of things from worn tyres/shocks/wheel bearings/swinging arm bearings/Isolastics incorrect tyre type or pressures, (to list a few) or a combination of more than one of those.
