Re: the ready room...
Archer never had a ready room, he had his quarters, and then we saw a dining room. There was a back area of the bridge for situation planning.
Kirk and his quarters of course, then we had the briefing room also for meetings..
Archer did have a ready room. The entrance to it is slightly behind Reed's station.
