Vinyl has more noise, in the statistical sense: however, it also has
a theoretically higher resolution than CDs.

No it doesn't.

a) What is the maximum resolution of the ear?

The million dollar question.

No, its well known.

At any one point in time its about 60 dB, but the ear's dynamic range window
can slide up and down another 40 dB or so. IME it takes about 80 dB to have
a practically transparent recording medium, and ideally it takes about 100
dB or a bit more.

The CD format has about 93 dB dynamic range in practice. So its generally
good, even overkill.

b) What's the lowest practical noise-floor of vinyl?

Around about -55db on the best ? (guess)

On a really good day about 10 dB better than that, on other days, about 10
dB worse. IOW the measured dynamic range of LP recordings ranges from about
45 to 65 dB.
