"Ok so I'm planning on wirelessing the house cause running wires on the stairs and through halls isn't working for me anymore...."

Using WAPs means stringing CAT5 to them, so you don't get away from this step.

A WAP in each room is a bit of overkill unless you are living in Buckingham Palace. Try to centrally locate your router and see who connects from there, you may not need a WAP at all.
