yes, let's start from there. What are you trying to recieve? The reason I didnt suggest specific equipment is because that arrangement (superdish pointed at dishnetwork locations) is a rather poor FTA platform. I've never tried it, but you might theoretically put an LNB somewhere in there to get 1 or 2 nearby satellites. It's really an experimental thing to do.
If you are really interested in FTA the easiest thing to do would be to get any 30" or larger dish and LNB:

you already have the reciever, so you are half there. Then point the dish to any of these satellites (yellow or green)

and you'll get whatever FTA is available. There are lots of resources here to help you in the pointing process, or you can ask on these forums.
