Sward83, first of all, thanks for the kind words and sorry for the slow reply! Let me so my best to answer all your questions.
RE: the number of recessed lights, I put in 11. 3 above the stage on their own circuit, and then around the room I did 3 on each of the sides and two on the back. It is a lot of light when all the lights are on. Plenty of light to clean and do whatever you might want to do. I did 6" recessed cans that I bought at Home Depot. I wouldn't change anything with regards to the lighting.
RE: the rope lighting, I have decided what to do (just this week) but haven't done it yet. I'm going to order some SMD LED take. I can lay it flat behind the crown, and it should work awesome. I put an outlet that is feed off a dimmer, in the corner behind the crown. That's how I'll turn on/off and dim the rope lighting. If I were to start over I'd do a couple things differently here. I would have mounted the crown a little higher, to make it easier to tuck rope lighting behind. I also would have used smaller blocks to anchor the crown to the wall (more room for rope lighting) and I would have mitered the corners instead of coping them. Additionally I would put a smaller, single outlet plug behind the crown instead of a traditional duplex outlet.
All of my lighting is controlled by Control4, as is all the equipment in the theater (and the entire home for that matter). This allows me to do cool stuff like have the lighting come on slightly when I pause the movie, have the lights slowly ramp up after a movie ends, have the lights automatically ramp off when the movie starts, etc... I did wire it all myself. In fact, I did everything myself with the exception of the painting and drywall.
All my equipment, including the lighting, is outside of the room and when in the room all controlled by the remote. Using the automation system, I have different activities happen based on the code I enter in to the lock on the theater room door. If I put in the cleaning code, it just turns the lights on 100% and leaves all the A/V alone. If I put in a second code, it means we're going in for the kids to do a program and turns on only the lights over the stage, and to a certain level. A third code means we're watching a movie and turns on all the appropriate equipment and automatically pulls up my movie library. And on and on.
I LOVE having my projector mounted in the soffit. It gives such a clean, cool look. You can't see the projector at all.
If I were doing it again I'd do a wider 2.35:1 screen. Vertical height is great, but my screen is 16:9. I'd stretch the width out to 2.35:1.
I LOVE the acoustically transparent screen as well. There's nothing up front to distract you... Just the picture.
I'm glad I did an exterior door, and two dedicated ducts and a dedicated in room cold air return. We're able to keep the temperature right and it never gets stuffy.
Hopefully that where them all! If you've got any other questions ask away. I enjoy them and look forward to more!
