Not that I know of.  It was one of the main rationales for making M-g
M-g do goto-line, but the bindings have not yet been introduced
themselves.

Just set next-error-function on Emacs 22.  However, I think it would
make more sense if we tried interfacing to
compilation-parse-errors-function in the long run.  I would not want
to hold up releasing 11.80 for that, though, as it seems a pretty
invasive change.  I think we should still release preview-latex
0.9.something before that as a last update before we attempt any
changes that won't work with standalone preview-latex versions.

Sure.  It will be as bad as the underlying editor.

Most bad boxes are not related to errors, so it makes perfect sense to
debug them in one session.

I am not yet sure about the best choice.  C-c ! seems somewhat
natural, but it assumes that people are familiar with TeX error
messages.  And AUCTeX helps you not getting too familiar with TeX.
