Your problem is how to get the <td> elements containing the letters
that belong to one of your letter groups. I think that the easiest way
to do this is to set up a key that indexes each <td> element that
doesn't contain an <a> element by the value of the closest preceding
<a> element, which you can do with:

<xsl:key name="letters" match="td[not(a)]"
         use="preceding::a[1]" />

The XSLT then looks similar to what you have already, except that you
can use the key to get at the letters associated with each letter

  <xsl:for-each select="tr/td/a">
    <letters name="{.}">
      <xsl:for-each select="key('letters', .)">
        <letter><xsl:value-of select="."/></letter>
