several questions about My Tickets

Hi,

Thanks for a great plugin, but I still have a few questions / issues I hope you can help me with.

1. I use the offline payment option, but the button still says:
   Review cart and make payment (actually the Dutch version of this: Controleer je winkelmand en betaal). I would like to change this text but cannot find where to do this.
2. also on the page after this, the title is Review and purchase (Controleer en betaal) and one of the tabs on all cart pages says payment (betaling), but you don’t pay through here, so I would also like to change these texts
3. when entering the e-mail address during registration ‘required’ is translated as it should be (to the Dutch verplicht), but confirm is not translated (that should be bevestig)
4. I would like to ask the persons for their address, but the only way to do this is to make it required, right? I want to ask, but would prefer not require people to fill it in.
5. Could I turn off the country in asking for the address, or at least put it standard on the Netherlands? Only people living in the Netherlands will make reservations here…

Thanks for all help you can give here! The first 2 points are the most important in this!
