Hi, I quote your original post: "We took the energy and time to level the ceiling, put up new drywall etc... We then sealed it with an oil based sealer/primer. Waited a few days, then proceeded to paint on a laytex ceiling paint. " You directly state you used an oil based sealer primer. Show us a picture of the labels on the cans. There must be some product incompatibility going on. Rough texture shouldn't appear out of nowhere. When there's a problem I always suspect that the first coats were not allowed to dry fully, esp. if the primer was oil. If it is uncured it will cause mischief with the finish coat, esp. flat latex. Putting more coats on top to affect a remedy actually makes it worse. I'd let it dry a good long time and see what happens. Another thought: you absolutely never put oil primer over new plaster- the caustic components turn the oil in the paint to soap and it peels right off. If the drywall job involved a large quantity of setting-type joint compound, the house is unheated, and the work was finished immediately before painting, then that's a possibility; the moisture still inside the not-fully-cured Durabond is reacting with the oil primer.

Are you adding trim molding? I like color on the ceiling, esp if it's vaulted. So I would paint manchester tan on all but the accent wall and continue it up around the angled part of the ceiling on all sides. Then paint the accent wall the greenbrier beige and paint the flat part of the ceiling the same color. It would look great if you have molding to break up the areas painted in the simply white to offset the areas. That may be too much for you so you can just paint the simply white on the flat and angled portions of the ceiling and then paint the walls manchester tan with the greenbriar beige accent. I'd suggest going to houzz.com and searching on tray ceilings so you can get some ideas of how they are treated with paint.

Like the pergola over the garage door idea. If built to be sturdy enough to walk on it, then it could serve as a fire escape route should the need ever arise -- certainly hope it never does. You might also consider painting your step rails and side supports the same color as your siding unless you're planning to have a wood finish door and/or a rustic porch and post addition over the entry at a later date, in which case you'd want those additions to have the same wood finish. (Might apply to any pergola over the garage as well.) https://www.bing.com/images/search?q=images+rustic+porch+and+post+entry&qpvt=images+rustic+porch+and+post+entry&FORM=IGRE
