Stomach - fitness/appearance. Good advice needed?

[Frenzied.]

I am in my early stages of adolescence.
This is what I want to change:
1. I have a square torso - how can I change it to get some curves - inwards possibly?
2. Scars from chicken pox - does Bio Oil work?
3. Dark brown quite-coarse hair on my stomach - does rubbing pumice stones on it work?
4. Got a likkle pot belly with manly 6 pack pads. Im not sure if I want to remove the fat because then I wold have a 6 pack... A serious one. =l
5. I have an outie belly button - is there any natural ways to make it an innie? Besides umbilicoplasty.

If you dont know any of the answers does anyone know a fitness online coach who I can ask (for free), for advice?

Thanks in advance.
