Prepare My Video to be Broadcasted.

Hello Everyone. I really hope you can help me out here, I'm on a bit of a time crunch.

I am making a commercial that will be broadcasted on Satellite Television. I need to know, basically, what I need to do prepare my commercial to be broadcasted. Or at least where to begin.

Also, I know that some parts of my question will be dependent on some specific information from the broadcast station. If that is the case I need to know what information I need to acquire from them and then once I have it then what do i do with it?

1) How do I make my Video's colors Broadcast safe? I'm using Final Cut Pro.

2) I am shooting on a Panasonic HVX. If the station can accept HD footage, Am i fine? And if they can't what do I need to do to make my footage acceptable?

On top of those two questions I basically just need general guidance. I am experienced with video and editing and all that but broadcast is something I never tackled.
