Listening to one's parents

Q: I am in love with a girl and want to marry her. I told my parents to ask for her hand but they are not agreeing as they have heard that the girl does not have good character. But after meeting the girl I am more attracted to my religious obligations. Please guide me what to do.

Accepting gifts without the consent of one's father

Q:

1. At the time of my marriage my relatives gave me gold ornaments as gifts but my father does not like at all that I receive those gifts. Can I accept those gifts without the consent of my father?

2. If I don't accept those gifts to please my father, can I accept it after my marriage as I will be no more under his responsibility rather I will be under my husband's responsibility?

3. If my father told me that I don't like you accepting those gifts even after your marriage and I agreed to him, can I still accept them after my nikah or not?
