Second, Is there any software thats designed for projections that can give more effects and freedom then PowerPoint or OpenOffice Impress?
Third, What's the best way to stop the ambient light that comes out of a projector without a physical barrier? Is the a setting thats standard with most projectors?

First: You might be able to find a lens
adapter to fit. Canon makes a line of desktop projectors and they use an add-on lens for short throw. You might even check at a local camera shop to see if they have add ons for old 35mm cameras that might fit. Since I saw that this projector has an auto-focus, you will need to turn that off if possible. That being said, anything you add to this will add to the risk factor of flying the projector so ensure that you
safety the lens appropriately even if noone is supposed to be under it!!!
Second: I second the question that we need to know what you are trying to accomplish.
Third: The ambient light coming out of the projector is often directional. When the projector is sitting on a
desk the light should be mainly spilling in a downward direction and vice-versa for the flown/inverted position. They are designed that way to minimize the distraction of the audience. Be extremely careful of disturbing airflow, especially on the smaller home theater projectors. It would really suck for you to have it shut down on you mid-show due to overheating.
