I thought all Cinelli 'Champion du Monde' (66-42) bars were 26.4mm clamp, and I also thought all Cinelli 1A stems were 26.4mm clamp size.

So why the f*** can I not get said stem to tighten on said bars?

Rounded out one bolt, drilled it out and using a spare from another stem. Still can't tighten it enough. And there is not enough space to get a shim in either.

Am I just being a pansy or do these bars also come in 26.0? I don't have any vernier calipers so can't measure accurately.

The bars are 26.4 and the stems come in 26.4 and 26.0, as far as I know. But that doesn't explain the bars being too slim in your case.. Make-shift Coke can shim?
