The steering wheel vibration most likely will not be from the wheel bearings, however the humming noise from the front area could very well be from the wheel bearing.... a simple test for this is to drive to an are that is not busy and then slightly turn your steering wheel to one side and listen for an increase in the humming noise.... this will indicate a well worn wheel bearing on the load side ( the right side bearing if you turned the wheel slightly to go left.. and the left side bearing if you turned the wheel slightly to the right) Front wheel bearing noises are also common to C.V Axle replacement and then the large nut at the center of the wheel not torqued properly... good luck hope this helps.....
