Hi,

My car shakes like hell when in gear (D and R). The steering wheel shakes like I am doing some kind of hand massage. It's much better if the car is in P or N. I think this must be related to the engine/transmission mounts. I can see that the front mount is pretty much worn. I am wondering if other mounts need to be replaced as well.

Which mount(s) most likely to cause such shaking, i.e., a lot of shaking when in gear, much better in N and P?
Thanks

My car is 99 Eclipse auto 420A NT with 114k

Probably front AND rear...
Have fun, rear can be a pain to get too.

Not enough

If your going to do the rear, save yourself the time and trouble and replace them all.
