I doubt there's anything new to be said about 986 IMS bearings. Everything in this thread could be repeated by selectively copying from other threads. At least oil formulations change, making the "what oil should I use" threads a little more relevant.
The Pelican Parts IMS bearing is virtually the same as the single row bearing that Porsche used (with an improved stud). Perhaps that would have been a more useful answer to Traco than the statement about only being available as a unit including the shaft.
If the IMS bearing is being replaced concurrently with a clutch, the additional labor is trivial (at my personal shop rate).
Here's some good reading with posts from Wayne Dempsey and Mike Focke:

To Nedlands: Seriously, you could just type your thread topic into Google and pick the answers you like from there.
and finally, here's a picture of a cat looking up torques in my 986 workshop manual. It's as useful as anything else in this thread.
