Switch off all Price/Commercial fields?

We are a charity organization, that is to say all our events are free of charge. Nevertheless it is necessary that participants register to our events. Is it possible to hide the fields price, sum, etc. because all of them show 0.00 anyway.
Secondly the registration form shows a headline in German "Rechnungs-Information" = Invoice Information. How can we rename the headline. It is not listed in the translation.
Last but not least, same form the events are listed twice! In a table and sentences below again, how to get rid of the latter?

Hi Juergen

Maybe for your simple usage, just go to Events Booking -> Configuration, find the config option Activate Shopping Cart, set it to No and use Individual / Group registration instead? If you use Individual / Group registration, there will be no price information like that being showed
