Yes, just to be safe. 24F playback on component would probably be fine, but if the projector can do progressive, it would be nice to take advantage of that.

If you want the highest quality: yes.
The projector will resize a 1080 source to 720 for display (if you give it a component). If you use the laptop, whatever display software you use will also resize the video. However, the algorithms they use for resizing will not look quite as nice as if you resize in post. (You can use a slower, better algorithm, theirs has to be real time.)

The size will depend on the room brightness and your screen. (Highly reflective screens make the picture brighter, but are generally less color acurate and reduce the viewing angle.)
Try out the Projection Calculator at http://www.projectorcentral.com/proj...ulator-pro.cfm
We use the ViewSonic to fill a 150 inch screen at church. The ambient light is bright, but the screen is still easy to see. 2500 lumens is enough for a lot of applications.
