>>> So, what else would you suggest?
Tools for removing/replacing all the 'flavors' of bottom brackets you have.
15mm cone wrench. . .for pedals.
Make an explicit search for all the allen wrenches, drivers, and tiny wrenches you'll need on ALL you bikes and make sure they're in the kit.
Hire out all of your wheel, spoke, cassette, and headset work since it's low-frequency and sometimes takes a pro's 'feel' to get them right or require specific tools you'll use once per decade. . .just make sure your 'pro' is a mensch.
