does it still shake after replacing the rotors?

If it doesn rotate the tires from front to back just too see if it a balancing issue. Sometimes balancers at shops arent calibrated well so they might be off a lil. If rotating doesnt help then take ur car to a shop to balance the tires(different one from where the tires were installed) and also ask them to check the balance before popping off the wieghts that are installed already.

When wheel bearings(also known as a wheel hub on accords) go bad they hum and they have play which might cause a disturbance but i have never noticed them to shake the steering wheel. If something is humming then while driving straight when noise is humming then turn the wheels left and right(a good amount so the car loads most of the weight to different wheels) if the noise goes away when turning left then it is the left wheel bearing and if it goes away while turining right then it is the right wheel bearing.

Sorry for the long post but hopefully it will help you out
