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?

Wearing jackets

Q: One mufti mentioned in a bayaan that we as Muslims should not be wearing clothes like the kuffaar. Then he mentioned even the jackets we wear, these resemble the kuffaar, so we should actually be wearing like a jubbah type coat which is similar to a kurtha. Is this correct? Are jackets disliked?
