Hi, I can help you out with your questions and issues.
Ticket List
To get a list of tickets purchased for an Event you can go to the Event List and then hover over the title and click Attendees, you can then, click, print, or email that list.
Please note, it creates the list by orders so if one person purchases 5 tickets, they will be listed for all 5 tickets. (Each ticket will still be unique)
The tickets will only show in the attendees list if the orders for tickets are completed in WooCommerce.
Go to WooCommerce->Orders to complete them.
Guest Register
I went to the site and went through the checkout process and by default I could have ordered without creating an account.
Please try the process in a browser you are not logged in and see if you can order without creating an account.
Either way it should still ask for billing information.
Let me know what you find out and if you need any help on these issues.
Thanks
