One valid Nikah is enough and no need to repeat after being sure that it was recited properly according to Shariat.

'It is important to note that if there is a possibility of harm on your faith or religious practice now or in the future , then such Nikah should be avoided.

Many people promise before marriage to embrace Islam or Shia Islam after marriage, just to get married with whom they want to marry, but they fail to fulfill the promise after marriage especially after passing years after marriage or after matrimonial misunderstands which are usual between couples. You must be sure the non Shia girl who wants to be married to you is really ready to follow Ahlul Bayt (AS) not for the sake of marriage but for the sake of Allah to a follower of Islam of the Prophet (SAWA) and Ahlul Bayt (AS).

Your parents might have this concern and don't wish to see you in trouble in the future.

'If this girl is ready to follow Ahlul Bayt (AS) for sake of the Truth, she should start following Ahlul Bayt (AS) now and not wait. That should indicate her intentions and might help your parents to believe that she is a sincere person in her promise.

Enemies of Ahlul Bayt are many types. Some of them hate Ahlul Bayt because of their hatred to the Prophet which is in fact hatred to Allah. Such people are with enemies of Allah in hellfire as all the enemies of Allah will be sent to Hellfire as we read in Quran ( That is the recompense of the enemies of Allah: The Fire (Sura 41, verse 28).

Some enemies don't dear declaring their enmity against Ahlul Bayt but attack Shia Muslims just because of their following Ahlul Bayt (AS). Such people who hate Shia Muslims for no reason but only because of their following Ahlul Bayt are with the enemies of Ahlul Bayt as we read in statements from Ahlul Bayt (AS).

Some people don't know enough about Ahlul Bayt nor about Shia Muslims due to wrong or misleading information which made them have negative opinion about Shia Muslims or think that Shia Muslims are not following Ahlul Bayt. If they know the truth about Shia Muslims, they will not oppose them at all. Such type of people are not with enemies of Ahlul Bayt because they don't know the truth.

'Who will enter Paradise and who will not, is not a personal opinion, but we take what is in Quran and authentic Prophetic statements.

This is a matter of different narrations in Sunni and Shia books. The Prophet Muhammad (SAWA) had many fostered or adopted daughters who was looked at as his daughters according to Arab society before Islam. Many persons mixed between the real daughter (Fatimah) and the fostered and adopted daughters.

Authetuc narrations confirm that the real daughter of the Prophet and Khadija is Fatimah, while other daughters were fostered or adopted daughters. Lady Khadija (AS) had a sister Haala Bint Khowailid, who passed away leaving her daughter who were been looked after by Khadija and the Prophet (SAWA).

There is a nice book with evidence from Sunni books, written by Allama Sayyed Jafar Murtadha in this subject. بنات النبي أم ربائبه

We, Shia Muslims believe that with out following the real Sunnah of the Prophet (SAWA) no one can be a real Muslim. Rejecting the Prophetic Sunnah means rejecting Quran because of the orders of Allah in Quran to obey the Prophet (Sura An-Nisaa' 59 and Sura Al-Maa'idah 92 and Sura An-Noor 54 and 56, and Sura Muhammad 33, and Sura Al-Taghaabun 12.

'Allah (SWT) Stated in Quran (He who obeys the Messenger, has indeed obeyed Allah) Sura An-Nisa 80.

The main point here is the authenticity of the narrations of the Sunnah. We don't take the narrations from liars or wrongdoers as part of the real Sunnah. We follow the most authentic narrations from the Prophet Muhammad (SAWA) which came through Ahlul Bayt (AS) and the authentic narrators. 
Many narrations were fabricated by wrong governments and their servants for justifying their wrong deeds, still claimed to be from the Sunnah. Muslims really need to be careful in calling narrations as part of Sunnah before assessing the narration and all the narrators.

'A well known Sunni Aalim (Scholar) Dr Tijani Smawi wrote a book after studying and comparing Sunni and Shia books of Hadeeth, stating that the Shia are the real followers of the Sunnah. الشيعة هم أهل السنة. This book is available in many websites. This Sunni scholars has become A Shia and written many books which guided thousands of Muslims to the real Islam of Ahlul Bayt (AS). The I was Guided is one of his famous books.

Non Muslims don't believe in Quran as The word of Allah, that is why they think away from the facts mentioned in Quran. Allah has clearly stated in Quran the reason of the marriage between the Prophet Muhammad (SAWA) and Zainab Bint Jahsh (And when Zaid has dissolved his marriage with her, We Made her a wife for you, so that the believers should find difficulty in marrying the ex wives of their adopted sons) Sura Al-Ahzaab, verse 37.

'Ahlul Bayt (AS) did mention this marriage being an order from Allah (SWT) to break a wrong common practice against divorcees of the adopted sons.

'It is worth mentioning that this objection on this marriage is not new but it was raised by the enemies of Islam from the Jewish and Nazareth and hypocrites during the life of the Prophet himself (SAWA) and was refuted by Quran, the Prophet and Ahlul Bayt (AS).

It is not strange from the enemies to accuse the Prophet and put false allegations against him.
