I am currently in the process of swapping out my very old motor mounts and installing FF mounts. I was also considering ordering the following transmission insert:
Any thoughts on this? I just use the car 1-2 a week around town and some highway driving, nothing too crazy. Worth it? And if so, how difficult is it to install?
This was my feedback when I was ordering my RSS engine mounts. I asked about the transmission mounts and their recommendation with the RSS mounts was go with the OEM transmission mounts. Running their engine mounts with another transmission mount can introduce different or even extra NVH's. I would assume going FF engine mounts with FF transmission mounts would be the ideal route for your situation.
I did the Sport (medium) one in my Turbo. Definitely felt like it cinched up the transmission and made it a bit more tight and rigid and "connected," though the improvement wasn't tremendous and it did add some NVH. If you're going for that kind of racey hard-edged experience, it's a good addition, but if you want something more refined and quiet I'd skip it.
I had my shop put it in while doing an oil change and I'm pretty sure it took them like 20 minutes max to do.

I installed the Flat6motorsports "SOFT" inserts about a year ago for no particular reason other than a preemptive measure.
My car is a 2009 997.2 C2 that although it only currently has 28K miles, I decided that 10year-old rubber part, ****ty roads, relatively low price and daily driving were all reasons enough for replacement. As to the installation, I had it done by my indi when I went for an oil change. However, I do remember that the instructions recommended the loosening of the engine motor mounts to jack up the engine about 1.5 inches or so to facilitate the remove/install the inserts.
As to what changes I noticed afterwards? Truthfully, none! But I do feel better that a more robust part is now in its place. Different strokes for different folks... for those of you old enough to know/remember what that means.
I've replaced these on three cars now (mine and two friends). I feel the OEM pieces are a joke. I believe new bushings will help support the transmission and prolong the life of the actual mounts. It does require removal of the rear bottom panel and depending on luck (as best I can tell) the new ones may go in easy or not. The swaps took me anywhere from 30 to 90 minutes.
I used the (black) race units on mine. If you're going for it you should do just that IMHO. I had previously gone the hardest motor mounts I could find.
The results ...
The motor mounts made a huge difference. All positive. Very little extra NVH. Maybe the old mounts were so loose they were creating extra NVH that got absorbed by the stiffer mounts. Or maybe it's just the car.
Transmission mounts (or bushings if you prefer) made very little difference. But I'm glad I did them considering that the original ones were flat pieces of nothing.
If you catch the transmission mount before it fails, you can use the Function First mount inserts to give it additional rigidity for better component control and to prevent the failure of the OEM mount. The inserts are available in 2 or 3 different stiffnesses. Transmissions tend to have and transmit more NVH to the chassis than motor mounts do, so when I did them, I went with the orange soft versions and have not detected any additional NVH. I think maybe Wayne went with the stiff black ones and believe he's happy too, so maybe not much difference in which you choose.
Inspect the OEM mount for any cracks or tears in the rubber surround Hi lift trans jack with a lift makes this pretty essy FF inserts instslled I lubricated them with a silicone grease during installation to keep them quiet and help them slide into position easily.
