I would likely use either 2x4 or 2x6 instead of 2x10.

• Drill pilot holes in those braces that you will drive the lag bolts through into the studs
  
  
• Finish the 2x4 or 2x6 you use before mounting it to the wall. When faced with this, I actually used a piece of 1" good quality plywood that I sanded down, routed the edges nicely, primed, and painted before sticking on the wall. Whatever you wind up using, make it look good even if you think you're never going to see it.
  
  
  
• Buy these and install them before hanging the tv on the wall. Read the instructions thoroughly.
  
  
  
• Buy these and stick them into the other things. Read the instructions thoroughly.
  
  
  
• You can get brackets that attach to the back of the tv mount that hide things like cable boxes, set top boxes, etc. We have Google Wifi hubs mounted behind our two wall mounted tv's to free up space on the surfaces the stands one stood on. They make brackets for everything, including generic brackets and even specific ones for like Nvidia Shield Console.
  
  
  
• Check cable length. If snaking cables through the wall, you may need to get longer HDMI cables.

Put it wherever you're going to put your devices. For low voltage hole you would cut a hole the size of a regular single gang outlet. You would need these Low Voltage Mounting Bracket
Then the faceplates screw to that.

EDIT- I have one of these to trace and make sure it's level.

Fishing is a pain in the ass, and a skill just like everything else. No harm in letting a pro do it.

If you use something like this https://www.amazon.com/iMBAPrice-LV1-2PK-Voltage-Mounting-Bracket/dp/B00HYHEC38/ref=sr_1_3?keywords=low+voltage+wall+box&qid=1564496246&s=gateway&sr=8-3 (once again, just an example. Single gang low voltage if what you are looking for) then use a drywall saw to make a hole that this thing fits into, it gives it a nice professional finish and the plate goes on there nicely.

Don't use drywall anchors or even a new work gang box. Look for low voltage mounting brackets, aka "mud ring"; here's an example:

Invert these on the wall (put the face against the wall) and trace the inner rectangle. Then take a drywall saw and cut out the trace. Insert the ring, tighten the screws, put on the face plate, done.

I've done IT work in a field and office setting for years, and this is the best, cleanest way, and it's perfectly acceptable (at least here in TN).

if they are low voltage would i need this?

If you already need to call an electrician to run an outlet, just ask them to make another hole for your A/V cables. If you are lucky they might do it for free. Will the cables just need to go from behind the unit down to the shelf that will hold the Apple TV?

I would ask the electrician to cut some extra holes for you, and you could tidy them up with something like this:

You would mount them to something like this:

I just got done mounting and installing a bunch of TVs and A/V cables for some of our branch offices, and that is pretty much what we did. The passthrough will easily allow the large tips of the cables through.

Of course you could also use a drywall saw and a cable fisher and do it yourself. If in doubt, call an electrician. Good luck!

Lots of good comments. I'd recommend a couple low voltage boxes to secure the boxes you bought to the wall. Make sure you get old work boxes.
