I've searched this site and Campyonly.com, and have scoured Google, but I haven't been able to nail down precisely which parts are required to convert a post-2000 Ergo shifter (Centaur) from 9-speed to 10-speed. Some say it's a simple operation involving the replacement of just the index gear, while others mention other parts that need to be replaced, such as a cam.
Would anyone be able to answer this definitively?
Why not compare the schematics and them decide what you need. I have never heard tell of anyone attempting such a thing. Lp

Take a look at the spare parts document (http://www.campagnolo.com/repository/documenti/en/spares01-A.pdf) from Campagnolo (opens as PDF).
The parts list and diagram for the Centaur brifter is on page 33. There, it appears that three parts are different between the 9-speed and 10-speed models: the shifter body and what looks like two shifting disc/cam.

Try Rodd at Brandford. Check his website, it can be done http://branfordbike.com/page.cfm?pageID=63

Thanks for that link! In cross referencing it to the page at the Branford site devoted to Ergo levers (Campagnolo Ergo Lever Parts (http://branfordbike.com/page.cfm?pageID=71)), it looks like two of those parts are indeed different for the 9 and 10-speed, but even though the body appears to be different for 9 and 10-speed according to the Campy specs, Branford only sells one body.
I'm going to go out on a limb here and guess that the body doesn't need to be changed. So basically it looks like two parts need changing:
1. Index gear (Campy part #EC-RE061)
2. Ratchet ring (Campy part #EC-RE062)
Here's the pertinent page for that link (Daytona is the old name for Centaur, for those not in the know doing searches for this info in the future):
Does this look somewhat definitive? By the way, Branford apparently does these conversions (Rebuilding Campagnolo Ergo Levers (http://branfordbike.com/page.cfm?pageID=63)) for $60 labour plus the cost of parts, so this isn't something that is unheard of at all.

Price the index gear and rachet ring, plus g-springs, then compare that to the price of 2009 Centaur or Veloce shifters in the $100-170 range. With the new levers you get a cable set worth about $40 and new brakes hoods worth another $30-35. It makes the new shifters look really cheap.
The new shifters offer better ergonomics and not g-springs to wear out. After trying the 2009 Centaur, I sold off all of my old Record levers and I won't be messing the old ones anymore. The new design should rarely need maintenance, but if a repair is required, it's a lot easier to do. I've had the new shifters apart and found them much easier to disassemble and reassemble.
