Ideally, yes. But it appears to me that what you want is an entire site lockdown that doesn't let the user see anything unless they are registered and logged in. You can do that with this plugin but it's more troublesome than using a plugin that is intended to do that.
This plugin is designed to drive registration conversion to view premium content, not to do site lockdown. The philosophy of the plugin is that users are funneled to "teaser" content and then presented an opportunity to register (or login if they are already a user). If that's not what you want, you might have better luck with a different plugin. Otherwise, maybe take some time and go through the Quick Start Guide to get the plugin setup and get a feel for how it works .
You don't necessarily have to have a specific registration page because the plugin will automatically put a registration form in the place of blocked content.
