Answer 1

I have used this method

public void SetNavigation()
    {
        using (SPSite Site = new SPSite("http://YourWeb"))
        using (SPWeb Web = Site.OpenWeb())
        {
            SPNavigationNode navNode = Web.Navigation.GlobalNodes[0];

            if (navNode.Properties.Contains("Audience"))
            {
                navNode.Properties["Audience"] = ";;;;YourSiteMembers,YourSiteOwners";
            }
            else
            {
                navNode.Properties.Add("Audience", ";;;;YourSiteMembers,YourSiteOwners");
            }
            navNode.Update();
        }
    }
