Help on A/V Wiring Location

[florad]

Hello. My basement has been studded and I'm ready to begin running some A/V cables in the wall before the contractor starts running electrical. I've attached a diagram of what I envision the wall plate layout will be on the wall behind where my tv will stand. I know I have a lot of stuff. The perpendicular wall to the right of the wall you see will be where all my wires will be centrally located. When running them, my question is, how should I run the wires? I want to stay as far away from the electrical as possible, so is it better to drill through the studs towards the top of the ceiling and then when I get to the stud where the wall plates will be run the wires down? Do contractors usually run the electrical down closer to the floor? All my wires are CL2 rated, so I'm hoping that feedback won't be a problem even if I have to cross electrical when I'm pulling the wires down. Also, is it ok to stack the plates like I have shown? Any suggestions would be greatly appreciated!
