You need to install these features you are asking for.
You download them from:http://www.jevents.net/downloads
Make sure for the likes of RSVP Pro, you download both the plugin and component and also, make sure to read the documentation supplied with it and it's a swiss army knife for event registration
there is a lot about it.
Again for the layouts you need to install what you want to use, so download them from the above links in the layouts category.
You install all of the downloads via the Joomla! Extension Manager.
