Delete Community Menu

How can I delete the community menu at the top of the page? I'd like to add the pages manually.

Also, regarding Buddypress, how could I place the "Create a group" link and the "New Forum Topic" link on user's profiles? I want to make my community more private, so I don't want the Groups and Forums pages to be shown to anyone, but right now those pages are the only place that users can create groups and forum topics. I'd still like users to be able to create groups and forum topics, but from their private profile page.
