Darla, ditto on the book recommendation. There's supposed to be a new edition out soon, but even an older edition will work for you (the main changes will probably be the examples Rabiger uses)
Would not recommend you do your own camerawork the first time out. As Ben said, you may be able to find a professional who would work for lower than normal prices if they are intrigued by the idea or at least by the prospect of getting to spend some time in the Italian countryside. You will have enough else to worry about than dealing with the camera too.
And you should probably get an interpreter as well, especially if you are dealing with a dialect. If (reading between the lines) part of your goal is to showcase a local culture, you don't want to force those folks to talk in broken English or even in whatever the equivalent is of the "Queen's Italian". You want them to feel totally comfortable in what is most comfortable to them.
