If I set up a Group apart from the advantange of being able to send targeted emails/notifications can it also appear in the Navigation bar with it's own set menu structure? I've tried the Voicebot but it was unable to help.
You would use permissions to achieve this. Create a page/section and then remove read access to The Public and grant read to the group.
This holds for anything else that you can apply permissions to. e.g., a photo album just for group members.
