Don't give the user Admin or page edit permissions and they won't get those items. If there is something on the admin menu that you need them to have then use a third party module to provide it, or wait for DNN 5, which will offer more control over that menu.

hmm.. they should not be getting the Host menu at all unless you're giving the host account to them.

You might find it easier to let users create their own portals as Admin or as another non-admin role by using Onyaktech's Portal Sign-up module: http://www.freednnsite.com/

That's the best option for providing portal-creation functionality. I think that site lets you go through it as a demo.
