I had a similar same problem.  I couldn't get M-x reftex-toc to work.
One tiny problem may have been that it was looking for file.Rnw.tex
rather than file.Rnw -- so I added the following to the end of my .rnw
file:

%%% Local Variables:
%%% mode: latex
%%% TeX-default-extension: "Rnw"
%%% End:

This seemed to get the reftex-toc to work, but I recall having
problems getting other reftex cite commands to work.

Let us know if you get any further.
