spread word around your school as quickly as you can about the narc, his life will be a living hell. as for dealing with your dad, what i did was i told my parents that i was going to smoke no matter what they do to me, and they can either accept it or live their lives punishing me every day. they decided they would not keep me from smoking as long as i proved to them i could do well in school, have a social life, etc. also just educate your dad about how harmless pot really is, give him alot of websites to look at. hope this helped, and good luck man. peace.
