I have the opportunity to upgrade my crank to a Campy triple (30-40-50). Will this work with my current 105 STI 9 speed setup? I have triple 105 shifters.
Should work with no problems. The minor spacing differences are of no consequence. The BB will need to be Campy compatible (square taper).
You may have to mess with the front derailleur to get it low enough, can be a bit of a problem if it is a "braze-on" type, but doable. We had the 50-40-30 Campy Racing T on my wife's old bike, rest of the components were Ultegra 9. Shifting was good but not quite as quick as with the original Ultegra triple.
The new 105 10-speed crankset shows to be 50-39-30. That should also work with your 9-speed.
