Hey Steve, why follow a procedure when you can have an application do it for you? :-) I've used this a fair amount and have been happy with it:

It's called FCS Remover, it's free, and it pretty much wipes your hard drive of all final cut pro components (or at least the ones you specify). Use with caution, though -- it'll wipe out your serial number and the hours of soundtrack loops, motion content and everything else that has been installed for Final Cut Studio if you let it. Just make sure you REALLY want to uninstall everything, or carefully pick the pieces you want to get rid of.
The last time I saw Apple publish an official procedure for uninstalling was for Final Cut Pro 3, but most of the steps are still accurate:

Just let me know if you have questions!
