[1] is the main file, including german rules, the resource cards and 4 boards.
[2] is 4 more boards
[3] is a copy of the boards only from [1]

This seems to be related to the PIZZA-version of Catan, where a Pizza-chain has a board and the resource cards as cutouts on the pizza boxes. (My german isn't quite what it should be, so if anyone wants to post a better translation, feel free to do so.)

Nope, and you only play until 7VP also.

Is there an English translation of the rules anywhere?
