I have not done it yet - I plan to do it. From what I know there are 2 mounts left and right + a transmission mount. I have pictures on how to do it for e300td only from Alldata.com. Yours is gasoline so I am not sure they will apply. You may also consider to replace the differential mounts (I guess you'll need an extractor tool).
If you have only 60k miles I believe it is premature. A diesel which works much harder the mounts needs to have them replaced arount 80k. Gasoline engines need to have mounts replaced around 100-120k.
Good luck.
