Check in your Islamic laws book of your marja for details and conditions of when to perform this. It is like a normal  ghusl with a different intention. 
 

Wudu isn't needed after ghusl al janabah and you would automatically have wudu unless you break it during or after your ghusl. For other non-janabah ghusls wudu must be made after if you wish to pray. If your marja states ghusl al hayd gives wudu or ghusl al juma' then you may follow this.

Only Allah swt is All Knowing and no creation can know the reality of His essence. The Prophet Mohammad (sawa) was however given divinely inspired knowledge and revelation from Allah swt. He was also given knowledge of the unseen,

Being in a state of janabah or hayd doesn't make your hands najis. The only times you would spread najasa is when you touch blood or one of the najis substances with a wet hand or body part and then spread it. 
 

You can touch things with wet hands in either state and nothing would become najis. 
 

Only some ulema state that the sweat of someone who has committed zina is najis.

If there are genuine problems with your in-laws then you can discuss this with your husband with the intention of finding a solution. He may be able to intermediate and speak to those in-laws to find a common ground or way to reconcile differences. By not discussing these issues it can become worse, so it is good you are thinking to do so. 
 

Just make sure that when you discuss these issues, it doesn't exceed the limits of the necessary matters. For example if one would starts insulting them then it could lead to ghiybah or mention unrelated matters

What he is doing is a very big sin and he cannot miss salah on purpose. He may have someone to do the missed salahs after his death however he won't be free of the punishment which he will brings upon himself for each intentional missed Salah. 

Share him the following hadith: 

Imam Ali [as] said: Verily, some people worshipped Allah being desirous (Of His reward) – so this is the worship of traders; and some people worshipped Allah fearing (His punishment) – so it is the worship of slaves, and a group worshipped Allah in gratitude (to Him) so this is the worship of the free. (Nahju ‘I-balaghah)

try to remind him of the benefits of the salah and help him in a way to beat his laziness. Tell him to try and count the endless amount of blessings he has and how rationally one must thank the one who blesses him. How is salah a burden compared to the life and sustenance that Allah has given us?!

You were not sure if your hand was najis nor did you see any najis substance on it so you can consider that your hand remained pure.

Asalamu Alaykom, 

Firstly a Muslim female shouldn't have male non-mahram friends. So this is already out of the question. Yes, interaction with the opposite gender at the workplace for example is permitted. 

In regard to discussing private sexual matters with her female friends, this should be avoided. Unfortunately some women fall into this and divulge intimate details of their spouses. 
 

If the woman genuinely needs advice related to sexual matters, she can speak or ask in a general sense without making it specific to herself.

Makruh actions will not cause one to have a sin, but it is possible that one could gain more reward by avoiding them. They are actions which are better to be avoided and disliked. 
 

Furthermore although one will not get a sin for doing a makruh action, there could still be a negative impact for one spiritually. So by avoiding them it could build up one spiritually and strengthen their soul.

If one needs to expose their private parts to a doctor for necessary medical reasons then it is permissible. Of course one should only show the part which is absolutely necessary and not more than is needed. One should also visit the doctor of the same gender. 

Some ulema also mention for the doctor to look at the private parts via a mirror rather than directly.

If the ayn an najasa was still left on the clothes (for example pieces of fecal matter) then yes they would be najis. However if it was only stains left such as blood stains, then this wouldn't  be najis as the actual najis substance has been removed. 
 

May Allah grant you success 

Bismillah, 

Asalamu Alaykom, if najasa was still on some of the clothes then you need to rewash them again as they would be najis.

If only colour remains, then it wouldn't be necessary to rewash. For example you had some clothing with blood on it and the red stain remained while the actual substance was removed. In such a case the item would be tahir and colour wouldn't be an issue.
