Did you map all controls for your steering wheel? First thing I would say is to turn auto clutch on, and check if you can change gears. With that the car should move. But it is weird since you said you are using auto clutch.
About the revs, I think it's from the FFB settings being set to "Full". It's an effect to simulate engine vibration (I think). So just set that to "Low", and the FFB will be smother.
