Sunnat Muakkadah of Jumuah Salaah

Q: I try to follow Imam Abu Hanifa's (rahimahullah) madhab here in USA. Please provide reference for my heart to be satisfied. The following are my questions

1. How many Sunnah mu’akkadah are there in Salat ul Jummah? My understanding is 4 before the fard and 4 after the fard.

2. Can we pray Salat ul Jummah 4 Sunnah mu’akkadah as units of 2 rakat or do we have to pray all 4 rakat with one taslim in the end?

3. Do we have to recite Quran after surah Al fatiaah in 3rd and 4th rakat of 4 Sunnah mu’akkadah (if prayed with one taslim in the end)?

Khateeb making a mistake in the khutbah

Q: The Khateeb in our district Masjid in the Arabic sermon - khutbah, he reads it as "fakheemil ithm" instead of "ism". A scholar says that this is totally incorrect as Naoozoobillah you are saying that Allah Ta'ala commits great sins. The Khwateeb was asked to correct it, but doesn't do it. He continues to recite in this manner.

1. Is it true that the meaning actually changes and it can lead to kufr?

2. Should the Khateeb be allowed to continue giving the khutbah if he fails to correct this mistake?
