Th shiftting thing I would guess is normal, my 99 did this also. As for the steering vibration, the steering shaft may need replacing. There was either a recall or tech.bulletin about this somewhere. My fathers 04 does the same thing. As for the variable vibration, I'd make sure they re-balance the wheels/tires. One of your brake rotors could have lost a weight or something to that effect.
