Your summary of "weight" reminds me of the teacher who would tell anyone
who asked for the time how to build a watch and other time measurement
devices.
He would also present a long lecture on the meaning of time in different
contexts
and relativity time dilation effects . It certainly would be an
interesting discussion
in a Philosophy of Science course but I would hesitate to present it in
a typical
course of Introductory Physics.
Around the middle of your second page there is a minor error " 2.2
kilograms
weighs one pound at the earth's surface". This would only be true only
at
some distance above (or below) the earth's surface.
