For filtering of actions based on Role
1) You can create different groups and set permissions of those groups as per requirement like "collaborator","contributor" etc.. This will automatically show and hide actions based on previlages.

2) If some the actions are still not behaving as expected you can create your custom action evalutators.

3) Then override configuration of that action in your share-config-custom.xml file to use evalutors crated in step2.
