is there a halachic bases for having a malavah malkah. what should the melavah malkah need to consist of.

I have heard that Jewishness is transferred through the mother. That is, if a child has a Jewish father and a gentile mother, then the child is a gentile. On the other hand, if a child has a gentile father and a Jewish mother, then the child is Jewish. Is this correct?

Is there any basis to the idea of not saying Psalms (tehillim) after nightfall?
