I kinda did the same thing and ditched my satellite. I was going wireless streaming for a long time, but if you're going to go that drastic I would ensure you have all the tv's you care about hardwired in if you want quality streams. cat6 would be best but if you have gigabit connections on both ends cat5e would work if it's laying around. Hopefully you have the wires ran already or have a basement... I'll never again buy a house with a crawl space. Good luck!
