Have you seen the online `frames' version of the documentation
at  http://www-texdev.ics.mq.edu.au/l2h/docs/manual/
  --  click on the "Contents" button.

Other examples of the use of frames with latex2html are at:
     http://www.iciam.org/    and    http://www.iciam.org/2003/ .

Ar these close to the kind of navigation that you have in mind ?

For these documents you can download the source documents, Makefile
  and init-files, from the obvious directory.

LaTeX2HTML does not build complete pages sequentially, as happens
with other TeX/LaTeX applications (which generally require 2 or 3 runs,
before the navigation and cross-referencing are correct).

Since LaTeX2HTML requires just a single run, it is clear that it must
revisit all the pages to add navigation, after the bulk of the document
processing has been done.

So it is not sufficient to just find the right Perl variable(s), but 
you also
need to look at it/them at the correct time within the processing.

In particular, all of the sectioning links are added to all the HTML
pages, as one of the last tasks of all to be performed.
It would be very hard to insert extra coding to show the appropriate
values. this certainly cannot be done in the LaTeX coding,
but would ned to be done within the Perl scripts.

Hope this helps,
