on stage you want to be away from the band and out of their way, certainly, close to the stage lip where the crowd will be, about three feet high and centered in the stage, the real problem if there is one is not placing the mics too close to any particular amp or the percussions, and place it so you will get an even mix of all of the instruments, and run cards not hypers since cards have a wide sound stage and have no rear lobe so you will not pick up much of the chatter behind the mics; for stack taping, run hypers and run from as close to the center of the room as you can, I often run near a table for protection or even better lash your stand to a pole or support beam with twist ties or velcro and then no one will bump into your stand, and run just a couple of feet above head height to avoid taping background noise and conversations, good luck
