Just a European guy which works a lot with Typo3. I have done several Typo3 updates. If you send me a link I can look closer to it.
I looked closer to your extensions some are really old and there are no updates to newer versions like miniFAQ, Shockwave/Flash movie and PDF Viewer, I'm not sure if they will still work in Typo3 6.2. And also Cool Library and Cool Autoindex might give problems the compatible version of that extension is Typo3 6.0-6.1.
I don't know if all those extensions are still used on the website.
