Should be fine. There is tiny difference in the line end
handling, but I doubt it matters any in practice.

That is fine. Unless you have named the lua instance, you don't need
\zerocount (and if you did not understand that remark, you didn't).

The \unexpanded can be useful if you have \startluacode ... \stopluacode
inside expandable things like \write or \edef, otherwise irrelevant.
