'97 GTP w/ 115k miles

In the past few weeks I've been getting a humming noise and slight vibration anytime I drive the car above 40 mph all the way up to highway speeds. Both go away when the car slows to about 40 mph. The noise seems to be coming from the front drivers side and I can feel the vibration through the shifter, steering wheel and the floor of the car. I noticed today going 45ish around a bend that when I turned the wheel to the left the noise seemed to subside, and when I brought it back to center the noise came back.

I also get intermittent "ABS" and "Check Tire Pressure" lights (Tire pressure is fine). Before they would only go on when I romped on the gas but now they come at random. Both either are on or off, not one or the other.

I'm guessing a bad wheel bearing for the noise/vibration, but would that also cause the ABS/tire pressure lights to come on? I would think that would be caused by a sensor or something along those lines. I'm going to check the bearing (hopefully) this weekend. Anything else you guys think I should look for or inspect while I have the car up?
