Hello,
"owner required" is needed to create the new ticket. Just create new organisation (VMeTicket admnistration->organisations tab->new). This way you can create variable number of customer groups (organisations). This groups has different authorizations to manipulate with the ticket (
www.artio.net/e-tickets/documentation#d0e109).
What do you mean the new layout? If you mean the design of the ticket, it's in ticket administration (VMeTicket administration->product detail->ticket template tab). Here you can create the design of the event ticket that will be printed.
If you mean the layout of the ticket detail front-end page, than is performed by VirtueMart. So you must edit the page layout (quite complicated code). There are some modifications on the page, to be able to run all the VMeTicket functions, so it isn't recommended to use different page template.
