OK good news and bad. Bad news, the 360 has no HDMI solution for HD gaming, for whatever reason they havent gone that route, only the PS3 will take advantage of HDMI.
The good news is there are two other ways to play HD gaming.
Do you have the Core or the main 360 system? If you have the main one it will come with a cable that has both composite (red yellow white) and component (red green blue) phono cables. If not you can buy the component cable separately. The system can do HD over the component ones, and the WLT66 has component. It wont be able to do 1080p over these, just 1080i and 720p, but on your tv you wouldnt be able to tell the difference.
Secondly you can do HD over VGA, Im not 100% certain but the WLT66 probably has a VGA port on the back and you can buy a special 360 VGA cable. This does 1080p, and is to some eyes slightly better quality. Check out Amazon for reviews of both cables, there are some questionable quality ones knocking around.
Hope that helps.
