I’m planning on installing Ultegra 9 speed STI brake/shifters. The rear wheel spacing fits my 9 speed cassette, (what’s that, 130mm?) so that’s no problem. I’m currently running 9 speed friction shifting. I’ve got a few questions about the conversion:
Will I need to replace the front derailleur? the Campy crankset? the BB? If the BB, what size is it?
You probably don't need to replace any of that stuff. STI front shifting is fussy with triples, but doubles are generally pretty trouble free.

If the stem is the right length for you, there's no reason not to just use a shim to let you fit in newer handlebars.
It would be a crime to discard the original fork, so converting to threadless is not a reasonable option. Quill stems are readily available in lots of different dimensions.
