You need a minimum of a 10 sp shift disk. Tools, a 5 mm hex key, a 3
mm hex key, a wide blade screw driver, and a 50¢ crochet hook (not
absolutely necessary). If you have a few thousand miles on the G
springs, replace them. Have a spring carrier handy if the one you
find inside is broken.

Special skills? Not really. It goes very fast the 3rd time you do
it.

It can be done on 1999 shifters and later(not 1998 or previous). You need the
shift disc, EC-RE-061 and the front toothed bushing, EC-RE-062.

Not 'hard' but can be 'diffucult', particularly getting the spring in the back
reattached and wound up.

One thing you don't say is how old are your Chorus 9 spd shifters? Are
they the older "pointed" hood that came on levers made between
1991-1997? Or are they the newer "rounded" hood that came out from
1999-present.

If the older hoods, check velonews tech and campyonly.com, both have
instructions on repairing ergo shifters, including replacing all
springs, and shifting disc. However, if they are the older hoods, you
might not be able to convert from 9 to 10.

If they are the newer rounded hoods, check out Andy Muzi's
www.yellowjersey.org

He has both the official Campy Ergo repair manual on line and which
can easily be downloaded:

http://www.yellowjersey.org/ergo1.html

Plus, Andy has Paul Southworth's excellent write up too:

http://www.yellowjersey.org/ergo_ps.pdf

Andy is very Campy knoweledgeable, a frequent contributor here and a
great source.

Another source for Campy Ergo knowledge and parts is Peter Chisholm at
www.vecchios.com

Peter is also very knowledge and frequent contributor here and carries
just about every type of Campy small parts. His prices are equal to or
cheaper than Branford, and he won't sell you extra stuff.

The front toothed bushing is not absolutely necessary. It is an
inexpensive part but replacing it makes doing the conversion more
difficult. The spring that covers the through bolt is tricky to
reattach. If you don't replace the front bushing, the cable pull
between clicks will be the same. The distance you have to move the
lever to get a click will be longer at some point.
