im exellent so far (my dad's opinion!) with my head shots but
I need more no scopes and more headshots rather than shooting them in the body or the legs twice! please help me, give me some tips or something, just anything to help me get better at sniping! thanks guys!!!!!!???

Like the person before me said, practice. In Halo 1, I used to play campaign - the "Truth and Reconciliation" level, where you start off with a sniper and you can silently snipe a ton of Covenant baddies. So you could try that - play on Heroic, on a level with a sniper rifle, and just practice.
