(It was for a 4.8, so I'm not sure if it can be applied to an I6....I don't see why not though as the physics are the same)
I to have started to notice an increase in vibration at rest (in gear), along with a slight pounding when I cross a set of ruts (in an intersection) at speed. The fact that I've replaced every link, arm, ballpoint and bushing front to back (not related to this issue) leads me to the only ones that are still original. I had planned to do the motor, trans and diff mounts this spring anyway.

You are correct in this. I only suggest parking the car perpendicular to a curb. The brakes will always overpower the throttle, but just in case you mess up, you want to have a curb in front of you. So hold the brake, hard, put in drive, and jab the throttle, don't be a wuss. If the engine moves more than an inch you have a problem. Do same in reverse. This will work for 3.0 as well.
When my mounts died, doing the above test made it seem like the engine was going to flip out of the engine bay. Driver side was completely detached, and engine would lift a good 3" - 6" from rest position. Our mounts are also oil filled. So when they go, expect vibration to show up fairly quick.
