1. I own two famiclones, and they both work on my TVs.  Just be sure to check the power reigon for the system, as you may need a converter or universal AC adaptor to run it.
2. To my knowledge, they don't contain the microphone.  Mine don't, and I think the mic was only used for one or two games.  The only FC system to have the mic is the original Famicom system, as far as I know.
