Building a Theater/Game and wanted some advice etc.

The room is approximately 23' wide x 28' long.

What do you guys think of these specs:

Screen: 119" Fixed Da-Lite Cinema Countour DA-Mat 16:9 1.3 Gain
Projector: Epson Powerlite Pro Cinema 1080p UB 1600 Lumens
Receiver: Denon 3808
Speakers: B&W in wall (forgot the model numbers) / 7.1
Subwoofer: JL Fathom 112 12"

All equipment will be on shelves in the back right (facing the screen) closet.

I am fairly new to this so I don't know much. Am I in the right direction here in terms of the equipment compared to the size of the room?

I was told the projector needs to be around 15.11' from the screen. Below are some plans. There are no windows and the room is dedicated for game/theater.

Any advice / comments would be appreciated.

Thanks!
