One more word of advice from a 14-year veteran, plus audio pro: practice, practice, practice! If you have a friend who's in a bar band or something, ask if you can record them, and use the opportunity to test out your gear before the "big show." You can use that opportunity to test placement, levels, etc., as well as testing how your new gear works in the field and how easy it is to operate without being too obvious.
