Not to mention there are different varieties of Tempus Sans...
I just took a quick peek at your code. There's some ginchy stuff in there though nothing terribly invalid (though there are validation errors that should be addressed). Your Cufon script looks okay, and that's what should be determining the font usage in the <p>text. I haven't gone over your code closely, but it looks like the <span class="style6"> code is overriding Cufon. Take the <span class="style6"> out of a paragraph and let the paragraph stand unstyled:
and see if that makes a difference. As Ralph notes, you're seeing the page display on your machine because you have Tempus Sans on your machine. We don't, and I'm not seeing it on any browser -- Opera, FF, or IE. We're seeing it in our default browser fonts. I'm guessing that "garish Times New Roman" is the default in your copy of FF.

On an aesthetic note, you're going for "font soup" here, with lots of decorative fonts competing for the viewer's attention. If it were my call, I'd back way off on some of these fonts -- get rid of Comic Sans entirely and use a more neutral sans font (say Helvetica or Trebuchet MS) for the body text. Maybe use Tempus Sans for the header. But that's a design choice, and this is your design, not mine.
