Ummm... how long have you owned this car? The car is supposed to idle at ~2000 rpms to warm up the engine, and then return to normal idle once it gets there. Sounds normal to me.
As for the shaking, that's strictly an RPM thing. Sometimes your car will stop virbrating at even LOWER RPMs. My car will shake if it's at ~700 rpms, but at 500 rpms it purrs nicely. Anything below 500, though, and it shakes again.
