1 - Depends - if you want / need to see 119/110 as well as the standard 101, then you should get the oval 18x24 inch dish.
2 - Technically, yes. If you have D* shutoff PPV, maybe not. I've heard that eh wireless phone jacks will work for this application.
3 - You're going to need a bit more -
4. Splitters DO NOT work with most DBS installations. What you need are called MULTISWITCHES. For a standard, 18inch round dish, you would take both outputs from the Dual LNB and put them into the 2 (input) side of the switch. Then ALL tuners would plug into the output side of the switch (the 4 or 8 side). If you have an oval dish, both inputs form all LNBs would go into the input side of the 4x? switch, and again, all tuners go on the output side of the switch.. Count on this (3rd room) being extra cost.
