These are not shipped with Emacs.  Reftex is.  I don't know how big of
a project it would be to adapt Reftex.

This is what I use for selecting entries.  Admittedly, it's 'hackish'.

Looks nice.

Yeah, I that aspect of url'ing is nice, I agree.

That also sounds nice.  Reftex provide many ways to format strings
which could be useful for ASCII backend, say, but perhaps it's too
tied to LaTeX, as you suggest above.

If such a project is undertaken it should, however, be done right, I
am sure we would agree. Making citation "first class citizens" would
be a first step IMO.
