Yeah mine is about half that size, so Im thinking 2 should be good.This is a picture of a 40’ X 7’ reef step with 3 return lines.
I would recommend a minimum of two return lines with your size of reef step.
So these are what I have for the main drain(s):Great. Ensure you purchase the covers for the added wall drains to match the pool main drain.

This is the first time Ive seen wall-mounted suction lines, so can/should I use those same ones on the wall, or is there just a cover that can attach to the stub out the plumbers have there currently once plaster is done? They're 8" wide, which seems kinda big, but maybe thats a good thing?
I also got confirmation this morning from the plumber that the double stub out is in fact suction for the bubblers and the other is suction for the vacuum.
