how can i be completely annymos

How can i stay invisable on the internet so that not even the fbi can find me. I use tor and use simple browsers like w3m. I use cgi proxys. I dont use my normal email or anything else when i do this that could link me to anything. what else can i do? what should i read about? any links or books i should read?

everything that you just mentioned in the right scinero I would have known enuf to do. but whats wrong with cracking someones wep and useing there secured wireless?

and is there anything im missing about annoymas at home? or tor is the best i can do without any programming experience.
