Hi Richard - sounds like a cool project :) It sounds to me like you're trying to switch AC using a MOSFET - chances are this won't actually work and may damage both the circuit and your TV. I'd highly recommend using a relay instead, as these are designed to take AC loads. There are even solid state relays (SSRs) that can take tens of millions of cycles before failure and don't have that clicky sound when they turn on.
Yep, this will only allow for "turn on" or "turn off" style commands. If you want to do more than that, you'll probably want to look at the Alexa Skills Kit (https://developer.amazon.com/appsandservices/solutions/alexa/alexa-skills-kit)
