Default Help to use FTV as central XBMC

I just recently cancelled my cable and bought a FTV with XBMC loaded on it. I was curious if anyone has any advice or suggestions to layout and integrate my FTV to the rest of the house with chromecasts? I was thinking about using TeamViewer and somehow add Avia, but was hoping for a more elegant method of integrating all these.

I guess I would need to remotely control my FTV and be able to watch using the local HDMI output interface as well as be able to cast to my chrome cast.

Any kind of ideas or suggestions would be greatly appreciated! Thanks!
