User posts on user pages?

I am sure that this has been asked and answered at least a dozen times already, and i have searched for an answer, but i might not have the correct search terms.

Anyway here is what i am wanting to know.

I have many users who all have pages, what i want to be able to do is set it up where they just log in to the admin useing there user accounts and can click post and the post be on there specific user page, not the home page or any other page except there own. I also do not want them to be able to edit or remove anything anyone else posts.

If i cannot do this with posts i would at least like to set this with the pages where they only see there page and no other.

This is for a school and many of the people are barely able to turn on computers much less keep from deleteing a wrong page.

Thanks
