I am glad you are still looking... there are plenty of homes out there and it is certainly a good time to look/buy.
I will echo everyone's recommendations and contact an agent to do some legwork and answer some questions for you. Getting all your questions answered here may not work so well.
Elisha is a great buyer's agent and I think I've sent you some recommendations too...
Good luck in your search!
