Werd. It seems normal for those things to clunk out on a car with that many miles. Do you know how often your power steering fluid was changed?

For the motor mounts, they may not be broken, rather worn out. Are you putting the car in grear(reverse and drive) and reving the engine so see the amount of movement(with the brakes applied)? Do you know which motor mounts are broken? There are five - two in the front, two on the sides(on the drivers side next to the strut tower) and one opposite from it attached to the transmission, and one in the rear in the center a little forward from the fire wall. You could alway see for yourself and check for breaks in the rubber.
