Looks like you've been very thorough
I'd add that the amount of advisable precautions depends on where you tour. If you a in a remote area where access to a store is out of the question, carrying a spare tire would be advisable. If you can call for help, or are less than a few hours ride from a bicycle store (the stranded cyclist remains behind while the other gets spare parts), then you look good to go. (and a hand pump is a definite necessity. CO2 are useful close to home because the gas typically leaks and you must repressure your tire a day or 2 later.)
