not worth it.

I wonder what parts are needed to upgrade Campagnolo Record Ergo 9sp to 10sp? Where to buy these parts??

you need new ergo levers,FD,RD, big chainring,cassette,and chain. It's cheaper to sell your 9 speed stuff on ebay, and buy a new chorus group. Given advances and trickle down technology, 2006 chorus is probably better than an older 9 speed record group.
