Any HDMI cable will do. There aren't any variations in the cables
Yes all hdmi cables are the same
No, but the HDMI cable also carries AUDIO.
For 3D Blu-Ray discs and 3D TV's, you will need a cable that meets the HDMI 1.4 specification. Most new cables can handle this.
Any HDMI cable that has an HDMI logo will work. All HDMI products need to be tested and licensed by the HDMI organization. If a cable passes the test, it works. If HDMI cables work, they work as well as ANY other HDMI cable. The digital nature of the signal means that high cost cables do not deliver a better quality image than low cost cables. So, select the lowest cost cable in the store - it will be every bit as good as the most expensive.
Any Hdmi cable can be used to connect your Xbox to your Hdtv. However you can purchase cables both component and Hdmi made be Microsoft for connecting your system other manufacturers of Hdmi cables include Monster cables and Sony.
The HDMI specification means that any HDMI cable will work equally well.

I do not personally sell USB to HDMI cables. You can purchase them at auction sites like Ebay or Amazon. You may find the at Walmart as well. They do not offer special discounts for organizations.
There is no such thing as '120Hz' HDMI cables. Marketing hype has cables promoted for many things that make no difference in the picture or compatibility. The only features that require special cables are 3D and Ethernet over HDMI, both of which can be had with HDMI 1.4 spec cables. The signal sent to the television is going to be 24 or 60 frames per second (24Hz or 60Hz). It is the TV that creates the 120Hz or 240Hz refresh rate to create smoother motion.
