I could take a look at helping out on the html generation.
If you can provide any relevant information on what is required and how best
to go abouts it I could give it a try.

The problem is that the original document itself is structured (as is used
for the document structure and hyperlinking, for easy accessing sections
etc.), but you'll need the so-called "tagged pdf", which extends that (pdf)
structure further for easy extraction of the text itself. This currently
isn't supported by LaTeX, and thus the pdf looses all additional "structure"
information that was present in the original source. Generating tagged pdf
files from LaTeX is a common feature request but won't be trivial, so don't
expect this to come soon. Also, this is a LaTeX issue that we can't solve.

This is a known issue.
Unfortunately, as I said before this isn't possible to change easily as it
is a limitation of current LaTeX distributions / releases.

What I don't understand is why your screen reader fails that badly. I just
copied a section from the manual from kpdf to a text file, and apart from
some broken characters it was formatted well (including a button table).
Speaking the text using festival from kpdf looks also pretty good (except
from some small glitches). As I don't have Adobe's reader installed I can't
test that ATM.

You need to distinguish between the various "structured" versions of pdf.
The manual has structures, but not the so-called "tagged" structures that
would be needed in your case.

Adobe's website doesn't help at all as we are using LaTeX, not any of
Adobe's products. Find more information on that topic on the internet (and
if you manage to find something that could help please let us know).

If you want to help you could try building the html version of the manual.
Most likely we will use tex4ht for that task, but it seems teTeX 3.0 has
some problems with that. As I'm pretty busy with my RL atm I simply don't
have the time to look into this issue.

As from what I can currently say the html version of the manual will come
before a tagged pdf will happen as creating a tagged pdf just isn't like
adding a switch when generating. Unfortunately.
