Guys.. need some professional advice..

I'm planning to get Sony KD55X7000F
1) Gonna wall mount it
2) Gonna buy Roku Streaming Stick+ & plug to HDMI
3) Gonna subscribe Netflix for 4K and Directv premier for all US channels
4) Hacked and currently have 4 sockets
- 1 at 40" above floor to hide TV power wiring
- 3 behind or below TV cabinet for
i) Soundbar (plan to get wireless connected, not sure KD55X7000F can support?)
ii) Wifi Router
iii) Gaming Console

Can the plan above makes my TV set up without exposing wires?

And which package to subscribe for on demand Kdrama?


Thanks
