AP location suggestions

Here's a house layout.
There are already cat6 cables in the attic roughly at points A and B. Would AP's at those 2 locations cover the whole house pretty well?
Would you suggest U6-Lites or U6-LR's there?
Maybe I would add an in-wall in the office if it seems weak later.
I know it'd probably make sense to put one in the living room, but it's a tall vaulted ceiling and I wouldn't even have a ladder tall enough to install that. So there in either end of the long hallway seems easy to do.
Thanks.
