Catch Mustang: Widget for Menu in the right sidebar?

Hi there, I have recently bought the Catch Mustang Pro theme. So far, all works well but I've got two questions: 1. Is there a way to add an additional menu to the right sidebar in pages (by not using the plain HTML-widget which is provided by Wordpress)? 2. In my blog section, there is no metadata (author, the time when a post was published, comments) visible. Is this because I am logged in (I currently run the site in development mode)
