The squeak from the front might be and usually is the ball joints. If the ball-joint fails, the car drops and loses directional control, could cause a crash. Get it checked out is my suggestion.

As far as darting around, again check all front (and rear) suspension components for wear and/or play. Could be alignment, many shops offer a free inspection. Alignment usually only changes due to damage or a failiing component.
