I only went to two movies for the 3D experience, Toy Story 3, and Tangled. With Toy Story, it was annoying, but it made the monkey scarier, meanwhile Tangled was pretty to look at in 3D. But the stupid glasses are annoying. It's so obvious it wasn't thought out well since a lot of us movie-goers wear glasses, so it was so annoying to keep it on my face both times. And it made my eyes hurt after a while anyway.
And with the Disney re-releases, they were originally made without the thought of 3D because, uh, it was the freakin' 90s! Nobody cared about 3D back in the day! But nowadays, every-freaking-thing has to be 3D. It's stupid, and the fad should just die again.
Um... Could you give an example? Because I've always written my scripts this way. Mainly because I find it easier to work with.
This website should give you everything you need to know about script conventions. Granted, not all of it will be applicable to you since you're not actually gonna have this filmed, and I understand it would be a huge transition to write scripts this way. But I guess I kinda think it's at least worth knowing the way the pros do it.
