Nikaah & Marriage Issues

Q: I've heard that premarital relationships are haraam, but I'm not sure to what extent am I supposed to keep my distance from this girl I am in love with. My friend keeps telling me to express my feelings to her, but as far as I've learned, I'm supposed to go to the girl's father to ask for her hand in marriage. I don't want to involve our families and make it hard for her to reject me, so I was wondering if it would be halaal to just tell her that I like her and wish to marry her? And then we would go to her father if she accepts my proposal.

Q: Please clarify in the light of Qur'an and Hadith. A girl got married and the next day of her arrival in her husband's house, she was found guilty of immortality and the fact was proven that she had illegal sexual intercourse with may boy friends. After having proof her husband gave her divorce and the girl went to her parents house. Now what should the boy have to return to her in addition to her mahar? Should the jewelry they gave her at the time of marriage be given back to her or not? Jewelry is with the boy. The girl didn't take anything except her clothes and simple jewellery which she wears daily.
