Sounds like you have an automatic Zetec, right? They all shudder somewhat at idle to one degree or another. A mechanic friend of mine tells me that they are very sensitive to having the right back pressure in the exhaust system and sometimes something as simple as replacing a holed muffler will partially alleviate the problem. I've seen this for myself on my own car. I thought it shuddered too much and replacing the muffler helped a lot. (see ride below).

As for the A/C thing...makes sense since you're putting more load on the engine when its on, thus making the shuddering problem worse. If it's squeaking (on AC that is) I would check your belts for wear and proper tension.
