After having the timing belt and water pump replaced, the steering column now vibrates, RPMs idle low, and the engine whines too high for the gear I'm in.
You should make sure that the timing belt and water pump job were done correctly and are not the cause of the other issues you are having. Then the other problems can be checked out if not related. I recommend having a mechanic, such as one from YourMechanic, come by and inspect your car, starting with a diagnosis of the engine whine.
