Happy to help. Front projection is an area I know pretty well.
The room sounds very good. I always am concerned about lighting setups as things like sconces are nice, but really must be completely off during any viewing as they aren't properly directional light. That is, the light, even at lowest levels, will fall on the screen and significantly impact contrast. In comparison, downlights over the seating area on a separate dimmer will provide direct lighting for people seated and allow a clear path of entry into the room, while not casting any direct light onto the screen. Typically, these lights will also be the furthest from the screen allowing the lights to be brighter with lower overall impact on the screen.

Sconces are great for decoration and entry/exit from the room, but terrible for home theaters. They are good for very large theaters which need path lighting even when the movie is playing, but typically would be 20 or 30 feet from a movie theater screen, which meant they didn't really impact the screen. They also were often very directional lights pointed down at the walking pathway instead of the often artsy sconces used in home theaters.
I give a lot of thought process to lighting for theaters.
