For the First Question, your DV cam should have a jack that says something like "A/v out." It looks like a mini TRS jack but it is a little bit longer than the standard style TRS jack. You then have a breakout cable that has 3 RCA plugs, white and red (for audio) and yellow (for Video.) You only need to use the yellow. I'm not sure about cables for a lengthy run or what projector you need, but someone else should be around soon to answer those questions.
