Macbook Pro to Thunderbolt Display to LCD TV

Hi

I hope that I am posting this in the right spot and that it hasn't already been posted somewhere.

What I am trying to do is connect my macbook pro via the thunderbolt port to a thunderbolt display, and then to an LCD TV/Monitor via VGA or USB. So far I have been able to connect the macbook pro to the thunderbolt or the LCD but not both. The thunderbolt port on the display does not seem to accept a VGA cable connected with a display port adapter. I am thinking that I want to connect the LCD to the Thunderbolt display or the macbook via male to male USB. Is this correct or should I be doing this another way.

Thanks.
