The jumpy idle sounds like a vacuum leak. Less likely would be a sticky IAC valve.

As for the shaking, is the check engine light on? With the reduction in power it almost seems as though you've lost a cylinder. I'd check that all your spark plugs are firing. If they all are, I'd check compression. With all the shaking, I'd also take a look at the engine mounts.
