Yes, first you will need to have a satellite dish that has the DISH LNB/s on it. It sounds like you have that.
Second, you will need the coax cable to go from the DISH satellite dish to the DISH receiver. It sounds like you have that too.
The coax cable between the satellite dish and receiver needs to be the heavier exterior type cable, not the lighter interior type cable that goes from the receiver to the TVs... or an HDMI cable between the receiver and TVs. I tried once using the lighter interior type cable from a satellite dish to the receiver and it would not pass the signals properly.
It sounds like you have it pretty well figured out.
