Yeah, neither of those are proper function. I suspect the yanking on the
steering wheel part is directly related to the "chimes all the time, for no
apparent reason" part, and if you solve the latter, the former will go away
with it. You may wish to remove the steering column cover and examine your
ignition switch wiring for wear, damage, or monkey business.
