Question 1:
Well, you are returning an Object Zulassung in your case, don´t you.
So @return Tx_ExtKey_Domain_Model_Zulassung

Question 2:
I add this type of validation just to be sure that we have an instance 
of Tx_Extbase_Persistence_ObjectStorage otherwise we will run into some 
fatal errors
if we have something different. But i thought that in your case the 
validation is obsolete, because we already know that it is an 
Tx_Extbase_Persistence_ObjectStorage.

Sorry for mention that:
I have seen a lot of people learning essential PHP things through 
working with a MVC-framework (in my case symfony).
That´s not a good starting point. I would recommend to learn first some 
essential things like OOP in PHP and some other things.
Otherwise you will never ever feel comfortable with the framework of choice.
Maybe i´m wrong in your case, but start to learn the basics along with 
books and more. It helps a lot to get into the flow.

You are welcome
