Replacing your IMS yourself

[truegearhead]

I'm thinking about doing the IMS bearing upgrade myself, I've done engine swaps and clutch jobs before but never on a car I'm making payments on. I really hate doing big jobs on a car my bank owns, but I don't hate it as much as I hate $3,000 dollar labor bills. After reading the Pelican DIY on transmission removal it doesn't look so bad. Those of you that have completed the job is it that painful, or just a lot of wrenching? What do you guys recommend me buying to complete the job? I think my car has a new clutch in it, its got 80,000 miles and the clutch is rock solid with a release point right off the floor so I was only going to replace the disc itself.
