Well I have heard that pirates got their ears pierced to improve their vision. My ear is pierced and my vision still sucks. haha I do not think that piercings have the same effect as the pins used in acupuncture/pressure but I have not studied it much so I am not sure about the actual mechanics of it. I really do not see how tattoos would effect your energy body either, nothing profound anyway. The skin gets a lot more damage throughout our lives than what tattos will do.
I plan to have some tattoo work done someday. Been thinking about doing something with tattoos of chakras on my spine and maybe even getting the "snakes" of kundalini winding up my spine.
I would not worry about negative effects. Positive effects on the other hand I am not really sure of. If a tattoo or piercing draws your focus to a certain area a lot then it would draw energy there as well.
