Yes, you can nest dtml-in's and you pass the parameters to the SQL
method by explicitly invoking it as an expression, not just as a
name.  (It happens that I asked a very similar question of this list
recently, which is why I now know the answers.)  My example, stripped
down a bit, looks like

<dtml-var standard_html_header>
<dtml-in search_author size=50 start=query_start>
  ...
        <tr>
          <td class="center"><dtml-var year null=""></td>
          <td><dtml-var title null=""></td>
          <td><dtml-in expr="return_authors(seq=seq)">
                  <dtml-var name>;
              </dtml-in></td>
        </tr>
 ...
</dtml-in>

I hope this is enough to get you started.  Contact me directly if you
would like more explanation.
