I can try and answer 2):
Site.AuthForm is set in variable $AuthPromptFmt (in scripts/forms.php):

SDV($AuthPromptFmt, array(&$PageStartFmt, 'page:$SiteGroup.AuthForm',
  "<script language='javascript' type='text/javascript'><!--
    try { document.authform.authid.focus(); }
    catch(e) { document.authform.authpw.focus(); } //--></script>",
  &$PageEndFmt));

$AuthPromptFmt can be custom defined to use a different page as
AuthForm, or indeed have the normal Headers and Footers removed by
replacing $PageStartfmt with $HTMLStartFmt, and $PageEndFmt with
$HTMLEndFmt, as Pm pointed out in this thread. The output is always
aimed at the current page, and achieved by the PmWikiAuth function at
the end with
PrintFmt($pagename,$AuthPromptFmt);
which displays the current page ($pagename) using $AuthPrompFmt,
thereby bypassing the more normal $HandleBrowseFmt which HandleBrowse
function uses to display the page with the page text content, using
PrintFmt($pagename,$HandleBrowseFmt);

$HandleBrowseFmt uses the page content ($PageText), unless a redirect
is encoutered:
  SDV($HandleBrowseFmt,array(&$PageStartFmt, &$PageRedirectFmt,
       '$PageText', &$PageEndFmt));
whereas $AuthPromptFmt does not include the page content.

Both can be custom defined in config.php without hacking pmwiki.php.

So there is no next page set with AuthForm, it just gets used instead
of the normal page content, and once the user is authenticated, or the
password verified, the page displays as normal. And if action=edit was
called or someother action, the page displays in the appropiate way,
i.e. the edit window or whatever.

Hope this makes it clearer.
