If one does get a tattoo while young, try to stick to areas that will not collect fat, breasts, stomach, bum, etc. I know way too many people who got tattooed, then got kind of fat, or PREGNANT, that kind of thing, and now the tattoos are all stretched out and droopy, even after they've lost the weight. As far as piercing at home, I think ears are about as independent as you want to go. Everything I've pierced my self, other than ears, has gotten horribly infected. It shouldn't cost too much at a good shop either, but if you're as young as I think, you'll have to get your mom/dad to take you. Good luck!
