At normal sitting level the your eye level should be approximately level with the center of the screen.

If you have those more advanced wall mount that can tilt/swivel then it's not so much of a problem as you can alter the angle to suit.

Building those shelves with wooden panel is the most common solution nowadays to conceal wires or just buy those pre-made with panel from Ikea.

No need break the wall, just put cable runs on conduits inside after hack inside the wall then you can pull in new cable as you like.

3 pin plug no, usually if you wanna pull power cable just unscrew the plug, pull the wire, then screw the plug back on. 5 mins job only.

I pulled speaker cable for the surround speakers, wireman didn't charge me extra cos I ady rewire the whole house, he help me pull CAT6 cable too for my HTPC (from study to TV area) put he couldn't put the faceplate.
