Reading the two rakaat nafl after witr

Q: My question is regarding the 2 rakaats after the witr salaah, what is the law regarding it? 

I have read in you fawta https://muftionline.co.za/node/33039 that our elders would read this salaah. However in ahsan ul fatwa, Hadrat Mufti saab explains this is not mustahab and also that no fiqh kitaab mentioned this. He also gave an answer for the hadith which shows these two rakaats after witr. 

What is the correct view in regards to these two rakaats?

Reading four rakaats nafl salaah after the fardh of Esha

Q: I heard that 4 rakaats after Esha is equal to Tahajjud Salaah on Laylatul-Qadr. I wanted to know what's the tarteeb of reading these 4 Rakaats, is it 2 Sunnah and 2 Nafl before Witr or is it 2 Sunnah then 2 Nafl and another 2 nafl then Witr or is it 2 Sunnah and 4 Nafl with one Salaam and then Witr? 

Also, what will be the count of the Esha Rakaats taking into consideration either 4 or 2 Rakaats before, these 4 mentioned in the Hadith and also the 2 Rakaats sitting after Witr?
