The shotgun won't be worth much except for making your rig look more pro, which can be valuable! Go with the SM-58 handheld (with foam pop filter) for getting the audience and band interviews-- if it's the classic 58 you won't mind it getting banged up and vomited on at a rock club. If you can, get ahold of a Zoom H4n, and don't trust the feed from the venues mixing board. Use its onboard mics. You might also want some kind of hand-held light, since lighting is usually horrible in audiences. Also, I recommend getting on the stage with the band and getting cool closeups from extreme angles. The tripod from the corner look is never too interesting -- it gets boring really quick! Hope you have fun and get some good stuff!
