Hi,
Thanks for purchasing WooCommerce Tickets.
First off all our ticketing plugins are about the same no major changes.
You are correct WooCommerce requires the order be complete before tickets are sent, this coding does that automatically:

You could use that to solve the first issue.
Tickets
The tickets look the same for all our coupons. It is possible to edit the look of them.
To modify the tickets you can follow the themer’s guide:

To move this file and edit it in your theme:
the-events-calendar\views\tickets\email.php
Let me know if you have any follow up questions.
Thanks
