hello bmwnewbie!
firstly i would like to extend a warm welcome from everyone at the hometheatershack:R
your ambient light problem will be addressed more suitably with a grey screen rather than white.
i'm sure the more knowledgeable guys here will jump in soon to help you but while you are waiting can you specify the make of your projector if you have bought it already? if you haven't what is your budget for the projector/screen?
also what are the dimensions of the room?
