Work with Events Manager

Hi all,
I have installed AAM, and Events Manager too. I want to make user roles, which can edit only one of Events Manager category. Have do I set it?

And the second problem: can I give access for a role to a group of pages? So I have in menu a 3 pages every with 3 sub pages. How do I add access only to one of menu pages (and sub pages)?

Thanks.
