It looks like you're doing 5.1 pre-wire for a TV over a fireplace.
Don't put a TV over the fireplace. Especially don't if this is supposed to be the prime TV and Movie watching space! I'd eliminate the fireplace from the build altogether and put the money saved into...
You've got a living space over the garage. If it's not too late, talk with the builder about going above and beyond on the insulation between second floor and the garage. I've never known anyone happy with standard construction quality when you've got a garage under living space, especially...

Make sure there's an outlet in little spaces like a garage mudroom. We almost missed that, but having an outlet...
