I have killed the dragons, the monestary guy,yaga, sendi, I have completed all the rooms in hell plane...but when I go to leave and ask for the end it says i have more to do that I am not yet ready???? What haven't I done??????

You missed only two things, and one of them is adding spoiler to this thread.

I have the same problem sabal. I did go there, but she was to hard at the time, so i reloaded and did watchers keep first. now that ive done that i cant go back in, same message. dunno why though

Go back and check you really have done all the hell rooms. It's easy to forget to do one.
