There is an extremely wide spectrum of how buddhism is practiced and I'd argue most ways are "wrong" and violate things the buddha very specifically said not to do (e.g. don't worship him).
There are no "requirements" in buddhism. there is no hell for you to go to if you do it "wrong". take from it what you want and leave the rest behind.

My understanding is that the present life and the cycle of reincarnation is what Buddhists seek release from in nirvana. There is a hell, we are just in it.
I hardly need say that "going" to hell is misleading as its not a place, and many other religions do not believe in it (.e.g. Christian universalists).

At some point you take so little its not the same religion anymore.
