Hi,
1. To change the copyright, in module manager, find the custom html module in position "bottom-1" and edit.
2. With some text not translated, you can edit the text directly in norwegian language. If you can post a picture with marked some specify text need to be translated, then we can tell you how to translated them.
3. We are in the end of upgrading to Joomla 2.5 and VM 2.0.2 and will provide in package soon. Upgrading from Joomla 1.7 & VM2.0.0 to J2.5 and VM 2.0.2 have some problem since VM have many changes.

Thanks for using our products!
