hiding access point and other gear

Hi,

We are remodeling our kitchen and adjoining family room and I want to take the opportunity to do something about the wireless situation. The family room and kitchen are downstairs and I plan on running CAT 6 down from the upstairs where the cable modem and switch are located. I am thinking about running 2 cables. One cable will be terminated on the family room on the wall where the TV will be mounted. The other cable would be in the kitchen which is about 15-20 feet away.

I have several questions.

1. Do I need a second access point or is this overkill?
2. What is the best way to hide my gear?
3. Would I get better coverage with a ceiling mounted access point? If so, are there units that are flush or hidden? FWIW, I am having ceiling mounted speakers installed.

Thanks,

Jerry
