On the Xbox 360, I need help because I want to start again on xbox live with my experience at 0 and the campaign 0% complete. BUT... I don't know how to do this, please help me.

Cant be done, its all tied to your gamertag, even if you delete it, all the levels you have done will still be playable and your online exp will still be there

Go to your dashboard select the end tab (Blue Screen), go to memory, Games, then find HALO 3 and delete all your saved gamed etc, it will be like you never played it but you will keep you achevements

Campaign I believe you can do it by accessing your saved games through the dash board. You would just need to delete your saved game.
