I did this exact thing in a wiki I'm writting.  Here is the code for what I
did:

$toc = ""
headreg = /^\s*h([1-6])\.\s+(.*)/
$document.gsub!(headreg) do |m|
        number = $1
        name = $2
        header = name.gsub(/\s/,"+")
        $toc << '#'*num.to_i + ' "' + name + '":#' + header + "\n"
        'h' + num + '. ==<a href="#TopOfPage">^</a><a name="' + header + '">'
                + name + '</a>=='
end

This will go through a textile document ($document) and add a link to the
top of the page every time it finds a header and build a table of contents
as it goes along.  The table of contents it builds is a textile document
itself so you'd have to run it through redcloth as well, but it will link
to each header found throughout the page.  As far as nameing the header it
takes the contents of the header and strips out the spaces so that it is a
valid url.
