Sunnats of nikaah

Q: With consent from my parents and siblings, and my husbands entire family (but not his father), I had my Nikkah in November last year. As soon as we announced to my father in law, he was over the moon and incredibly happy. Some realtives also knew about the nikaah beforehand as they arranged our marriage. The Nikaah was beautifully done at the mosque in front of witnesses and my mother and sister. After the Nikaah my parents announced it to other relatives and friends. I and my family received a lot of backlash.

My question is, Islamically did we do any wrong in keeping the nikaah discreet from noise and simplifying it as best as we could? I have received love from my in-laws and family members who were generally happy. Some relatives and family members may forever hold a grudge of some sort. For my own contentment, I wanted to ask if I did anything wrong or were there any mistakes in hiding it from certain family members?

Q: I am engaged to be married. My bride to be is doing her degree from home. She wants to stay at home till completion. So our families decided to hold the nikah soon and let me stay at her place to consummate the marriage. After she completes her degree we bring her home and give the traditional dinner party. Is that permissible in Islam? Please sight hadith for me to prove it to my neighbors.

Q: I am a 26 year old girl. I got a proposal last year and it's already been a year. He and his family are assuring us that once he gets a job and settles, then only will we proceed further. My parents are very worried about me. I dont want to be the reason of my parents sadness. Actually the main problem is that he is from South and I am from North. In South marriage, there willbe a grand show off and all that but currently he is jobless. My parents still agreed and are ready but he is stuck on one thing that he needs a job. We must just wait 8 more months. I just want a halal relationship. One more thing I would like to ask is that we did a register marriage in January 2017, just to avoid wrong deeds but now I am feeling that without Allah's blessing how can we be happy. So I am insisting to get marry according Islamic shariya but he says that he can't do it now and he needs time. Please suggest what to do because I am completely lost. I really dont know what to do.
