I just installed a attic stairs ( Werner brand ) a few months ago. I shimmed all the sides just like you do a door ...to keep the edges straight for trim and more secure to the framing . Both ends have double headers. I prefer to have it lowered at 1/"2 so the drywall meets it . I don't like doing drywall where it meets the trim exposed. I want my trim laying over hiding the gap where drywall meets framing. The attic stair door is recessed 3 inches into the stair box frame....makes it look nicer in terms of exposure.
