RE: on headings, labels, links, and image maps

1) Headings - yes you are correct, level A requires coded headings so
that blind users can get an overview of teh page and jump to sections of
interest by listing the headings. Level AA requires these headings to be
nested correctly (ie form a logical semantic structure)

I did a bit of fact-checking to answer my own question:
Headings do not need to be nested properly to comply with WCAG 2.0.  This is desirable, but not required. If you look at the How To Meet information for SC 2.4.10 (2.4.10 Section Headings: Section headings are used to organize the content. (Level AAA)) you'll see the note below:

"In HTML, this would be done using the HTML heading elements (h1, h2, h3, h4, h5, and h6). These allow user agents to automatically identify section headings. Other technologies use other techniques for identifying headers. To facilitate navigation and understanding of overall document structure, authors should use headings that are properly nested (e.g., h1 followed by h2, h2 followed by h2 or h3, h3 f
followed by h3 or h4, etc.)."

Note the "should" - it doesn't say "must".  That's my take on it...
