Arrange marriage in our Haryana.

Yesterday, a friend of my father's contacted him about a marriage proposal. He was looking for my biodata to find a suitable match for his other friend's daughter. Today, I spoke with my father’s friend, and he asked for my salary slips. I'm really confused about whether salary slips are actually needed for arranging a marriage. I did send him the slips initially, but then I decided to unsend them. I'm wondering if providing salary slips is truly essential for a marriage proposal. Also, if I'm scheduled to meet the girl, I'm a bit nervous. I'm not sure what to keep in mind during the meeting or what topics to discuss with her or ask her? Please advise guys.
