LaTeX2HTML already has a mechanism for linking to stylesheets.

There is the $STYLESHEET variable, which (like many other variables) can
be set either on the command-line:   -style "style sheet name"
or in an initialisation file.

By the way, after redefining  meta_information  as above, 
did you look at the HTML source ?
I suspect that it ended up with 2 <LINK> tags for .css style-sheets.

This ability is already built-in.
The variable to use is called:  $LATEX2HTML_META .

It comes *after* all the other meta-informatin that is generated
by routines that come with LaTeX2HTML, but before the stylesheet;
viz.  (from latex2html.pin):

    join("\n", (($DOCTYPE)? $DTDcomment : '' )
        ,"<!--Converted with LaTeX2HTML $TEX2HTMLVERSION"
        , "original version by:  Nikos Drakos, CBLU, University of Leeds"
        , "* revised and updated by:  Marcus Hennecke, Ross Moore, Herb Swan"
        , "* with significant contributions from:"
        , "  Jens Lippmann, Marek Rouchal, Martin Wilck and others"
            . " -->\n<HTML>\n<HEAD>\n<TITLE>".$title."</TITLE>"
        , &meta_information($title)
        ,  ($CHARSET && $HTML_VERSION ge "2.1" ?
              "<META HTTP-EQUIV=\"Content-Type\" CONTENT=\"text/html; charset=$this_charset\">"
              : "" )
        , $LATEX2HTML_META
        , ($BASE ? "<BASE HREF=\"$BASE\">" : "" )
        , $STYLESHEET_CASCADE
        , ($STYLESHEET ? "<LINK REL=\"STYLESHEET\" HREF=\"$STYLESHEET\">" : '' )
        , $more_links_mark
        , "</HEAD>" , ($before_body? $before_body : '')
        , "<BODY $body>", '');
}

Notice that there are 4 ways to add extra stuff in the <HEAD> section:

 a.  redefine &meta_information
 b.  provide whatever you like as: $LATEX2HTML_META
 c.  provide whatever you like as: $STYLESHEET_CASCADE
 d.  give a file name to $STYLESHEET 

The $more_links_mark  indicates where the automatically-generated <LINK> tags
will be placed, once these have been constructed from the document's structure.

Hope this helps,
