I guess my first question would be about why you want to go 2.35 with a projector that doesn't allow you to zoom back and forth between 16:9 and 2.35 resolutions. Do you have an anamorphic lens?
Either way, generally I've heard that about 30+ lumens per square foot is recommended for 3D viewing content, preferably a bit higher as at least 50% of light will be cut with 3D.
Without a properly treated light space, then perhaps more would be good.
With a 120" 16:9 screen, you would have about 30 lumens on screen if you went with a minimal gain (1.4 gain) screen. This would provide enough light for 3D gaming, and could be adjusted downward if necessary.
