I just finished doing the same on my 3.2 L. The FI R&R was pretty easy.
Steely has a good list of the steps. The only difference I might suggest is to pull the locking clips, then pull the fuel rail - it will likely come off the FIs first. Then pull each of the injectors separately. At least that is how I did it and it seemed to me easier that when I tried to pull the three with the rail.
I sent mine out to WitchHunters as that seemed the most referenced and it went well - had to replace one.
When I got mine back together and went to start it, I found I now have a leak in the fuel line at one of the swivel joints. It is a PITA and depending on what I end up doing may be expensive (see recent post on fuel line) but it may have been a blessing that it started to leak now rather than when out on a hot day at the track....
So you may want to carefully look the fuel lines over at the same time as this is (as I now find out) a well known problem and failure point for the fuel system.
