I understand where you are coming from with this question. Investigating and researching the topics around the Shi'a Sunni division can be mind boggling when there are claims and counter claims from both sides and the quality of evidence put forward by each side also gets challenged by the other.

Here is a suggestion to help you get started that is designed with your preference in mind of avoiding sectarian bias in your research.

Step 1

Bismihi ta'ala

Some quick information about Muhammad ibn Abi Bakr:

1. Name: Muhammad 

2. Father's name: Abu Bakr ibn Abdullah ibn Abi Qahafah [the first Caliph]. 

3. Mother's name: Asma' bint 'Umays, who was married to Ja'far ibn Abi Talib [Ja'far al-Tayyar] (a.s.), and after his martyrdom she married Abu Bakr. She gave birth to Muhammad while in the state of Ihram. After Abu Bakr's death, Asma' married Imam Ali (a.s.). Throughout her life she stayed loyal to Ahlul bayt (a.s.).

4. His birth: Year of Hajjatul-Wada'.

Bismihi ta'ala

The high level of self-restraint that Imam Ali (a.s.) had towards those who wrong Islam and him personally can be seen in many events during his life. 

This also embodied in the last days of his noble life when although he was suffering from the painful strike of Ibn Muljam's poisoned sword, he still made sure the perpetrator was treated with compassion and fairness. 

The details of this can be read in:

Sheikh al-Mufid's Kitab al-Irshad [The Book of Guidance], biography of Imam Ali (a.s.). 

Bismihi ta'ala

It is always mustahab to perform wajib prayers in congregation. There are many traditions that emphasise on Jama'ah prayers, and how multiplied the reward will be when conducted in congregation. 

With the absence of a qualified religious scholar, there will still be a virtue of Jama'ah prayer. In brief, the person who leads should be known for his piety, and also have knowledge of the rulings of prayer. 

And Allah knows best.

Of course, this is not something of correct behaviour normally accepted by sensible people. 

However, as a fiqhi matter, some jurists have deemed it as prohibited, and some have said it is of obligatory precaution not to drink one's wife's milk.

And Allah knows best.

Bismihi ta'ala

If something that resembles semen does not come out in the process of an ejaculation, but while urinating, then there is no ghusl, and only washing of that area. 

And Allah knows best. 

Bismihi ta'ala

When a woman finishes her menstrual cycle, it is obligatory for her to perform Ghusl al-Haydh in order for her to be able to pray or do other acts that depend on the ghusl. 

And Allah knows best.

Bismihi ta'ala

Problems and difficulties will naturally occur between a husband and a wife, but the commitment to one another must stay as strong as ever. There are shallow problems, and issues, that should be overlooked, with patience, forgiving and forgetting. 

However, there are problems that become core issues and cannot be overlooked, like violence, abuse, neglecting religion, drugs, etc. In these cases, seeking consultation and professional assistance is necessary.
