Yes you will have problems with light in the rest of the room.
Turn the projector off. What the screen looks like is what your black will be. Very dark gray, dark gray, somewhat dark gray, etc. will "scale" up from there. When you calibrate the projector for a room where other activities such as billiards are taking place, the calibration will differ from that with the room almost pitch black and you may still be unable to get all the shades in a gray step pattern to be distinguishable..
For a not so dark room, forget about front projection. Use rear projection or direct view.
Over the years, LCD whether front projection, rear projection, or direct view has been on average getting better at crisp (not so smeared) fast motion. Of course some models will be better than others. You will need written reviews or word of mouth or hands on viewing in a store to find out which.
Statistics have it that turning a typical DLP or LCD front or rear projection unit on and off frequently will result in a shortened bulb life. Particularly harmful is turning it back on after less than ten minutes of being off. Meanwhile the bulb also has a finite lifetime being on continuously. I believe that the break even point is when the TV will be off for less than an hour it is better left on.
