1) You're still using Cufon? What is this, 2002?
2) Seriously, switch to webfonts. They don't have all the BS around them. Use Font Squirrels generator to turn your TTF into all the needed formats... that way they behave as normal page elements instead of the decade out of date VML+Scripting mess that is Cufon.
You're basically using 1.7 megabytes in 40 separate files on a page that there's no reason for it to be more than 20 files totalling around 100k... Just the markup alone; 17k of HTML for 1.34k of plaintext means it's such a convoluted mess, my advice (and I say this a lot lately) is to throw it ALL AWAY and start over clean -- it's so out of date on methodologies it would take longer to fix properly than it would to rewrite.
In terms of bandwidth use, speed, accessibility, functionality and maintainability, there's nothing there even worth trying to salvage.
Deathshadow has pretty much summed up your core issues with the site. Looks great, but at what cost?
I'd strongly suggest you consider his points.
With respect to Cufon fonts, I initially used them as a headline font replacement option in my commercial WordPress theme, then [deprecated them in favor of Google Web Fonts. I have [URL="http://www.sitepoint.com/forums/showthread.php?812344-A-Google-web-fonts-explosion!-Closing-in-on-400-fonts"]several skeptics here on their efficacy](http://clickbump.com/google-web-fonts/), but I have nothing but positive things to say about them in comparison to Cufon.
