I had the same problem...drove it for about a month before I heard any noise coming from the wheel (thats how I knew which one I had to replace) then I got it fixed.
As for the lights coming on without moving...here's my theory. I think that the ABS sensor is located on the wheel bearing assembly therfore when the bearing goes bad it affects the ABS sensor. once the sensor is bad the light will come on. track control needs the abs system to work so when the sensor goes bad it is disabled too. SVS light is there...I think just to remind you that you have other lights on
and you need to check it out. I'm no mechanic but I think that's how it works.
If your ok with driving without abs of traction control for a while then I'd wait for the sound to be heard before changing the bearing. That way its easier to tell which is bad.
hope this helped
