The DIrectWay dish will work well fixed for a single KU band satellite. There are several types of DirectWay dishes, so it would be great if you could take a photo of the feedhorn. Likely it is set-up to receive one polarity, so a 2nd LNB will need to be added or replace with a voltage switching polarity LNB.
The DirecTV 3 LNBF dish might be saved for a future project, but it isn't much use for most FTA. The Monterrey receiver is analog only and all KU band analog is long gone. Once again, keep for a future project.
You will need a good MPEG2/4 receiver and I might suggest the Amiko mini HD SE. Great value and quality. Less than $100 on Ebay. If you get a used receiver, make sure it is MPEG2 and 4. While there is quite a bit of MPEG2 programming, a lot of the good stuff is in MPEG4.
