Although I'm not sure if this helps with your IMS bearing question.
2000 was the transition year for the replaceable double row bearing to the replaceable single row bearing that had more failures. 2005 was the transition year from the smaller single row replaceable bearing to the larger non-replaceable (without splitting the engine case) single row bearing.
My guess is since this was built toward the end of the 2005 production run, it has the larger bearing, but I believe the only way to know for sure is to drop the transmission and look.
