Another noob here. It seems you are sort of correct. The problem is the bike handling could get pretty bad (twitchy) if you go overboard with the aero position.
From the reading I have done, it seems like the best approach is short aero bars. Preferably ones with arm rests that have a low stack height and mount behin the steerer tube/stem cap. And the extensions mount at or below the flats on your drop bar (vs sitting above the flats). Seat post can come forward a bit, but not too far - you might be able to use one of the fast-forward posts, but you probably should try with a normal low/zero-offset post first.
The benefit to this approach is the bike still fits as a road bike. You can use the hoods and drops for climing and descending. Handling remains acceptable.
Like I said, I'm new to this as well. This is just what I've gleaned from a week of research. I'll be applying it over Christmas/NY break.
