Not entirely fine in the way you did it. The <!-- you left in is making it throw errors here…
The two lines at the start:
//<![CDATA[
<!–
and the two at the end:
//–>
//]]>
Should be removed when putting them into external files to prevent that. Technically the ones starting with // are treated as comments and do no harm, but the one lacking that is causing issues.
Though you’ve got all sorts of other oddities on the page – invalid heading orders, a whole slew of unnecessary div and ID’s, comment placement proven to trip IE rendering bugs, paragraphs around non-paragraph elements, headings around non-heading elements, drop-down menu that will likely never be able to function given the flash embed, inlined style attributes for nothing, that it’s invalid to say “px” on widths in the markup … and that’s before we talk the non-real world deployable XHTML 1.1 doctype with the XML prolog further increasing the IE headaches.
… or the width that’s not even 1024 user friendly and fixed metric (aka px) fonts on the content areas… and the total lack of image optimization resulting in 126k of images doing like 60k or less’ job.
I would really suggest cleaning up the markup and fixing all those issues – which in terms of the HTML would look something like this:

Drops back down to the best XHTML doctype for cross browser support (or should I say the only XHTML doctype designed for cross browser support?), and throws a good third of the markup away…
If I have time later I’ll toss together how I’d apply CSS to that… including making it 1024 friendly… Though I’d probably also swing an axe at the flash banner in an attempt to make it semi-fluid width.
