Hi Again,
Thanks for the interest in WooCommerce Tickets.
The tickets have to be setup per event and you go through the checkout process to get a ticket.
It could be used as a RSVP system, but would take some changes to do that like prevent ticketing emails from being sent.
There is the Event Rocket Plugin an unofficial plugin maintained by some of our developers that has a basic RSVP system in it.

That might be closer to what you are looking for.
I am not sure about your 2nd question though, however, the tickets display on the single event template like this:

Let me know if you have any follow up questions.
Thanks
