Question

<script>
            $(document).ready(function() {
                $("#various2").fancybox({
                    'width': 800,
                    'height': 570,
                    'type':'iframe'
                });
            });
</script>

I’m getting error in IE8 and 7 but not in IE9

Object doesn’t support property or method ‘fancybox’

and error is on this line

$("#various2").fancybox({

and my scripts are at bottom before </body>

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js" defer="defer"></script>
        <script>!window.jQuery && document.write(unescape('%3Cscript src="js/libs/jquery-1.5.1.min.js"%3E%3C/script%3E'))</script>
        <script src="js/plugins.js" defer="defer"></script>
        <script>
        $(document).ready(function() {
            $("#various2").fancybox({
                'width': 800,
                'height': 570,
                'type':'iframe'
            });
        });
        </script>

I guess, you should debug around defer=”defer” part. Different IE versions may be interpreting it different way, causing js libs to be parsed after body script gets parsed.
