Typically when the crank position sensor fails, the engine stops running. The crank position sensor is how the ECU knows the engine is running. No signal = engine is off, so both spark and fuel are stopped.

I start my car everyday before I go to work, and it always is at a higher idle (1200 or so) and then after about 30 seconds it drops to 900-1000. So youre not alone there.
CLKFAN- does the crank position sensor, does that throw off a check engine light when it needs to be replaced? I have the shaking thing too, but not too bad yet, so I'm changing my plugs this weekend to see if that will help it.

There is one more thing that you have over looked and so has who ever has been doing your work...THE CRANK POSITION SENSOR. When it goes bad you will have shaking as well as strange power loss while driving. This is what my mechanic friend which happens to work as a Mercedes tech at a Mercedes dealer told me. I will be changing mine out as well as many other parts that need to be changed.
