Salaah

Haafiz who trims his beard

Q: Who should lead the salaah? A hafiz of the quran who has a nice voice, but who trims his beard under the required length and who's robes flows under his ankles, or someone who isn't hafiz but is righteous adheres to the Sunnah? If the first leads the salaah should one repeat the salaah?

Reciting behind the Imaam

Q:

1. I just want to ask in the zuhr and asr salaah when you are behind the Imam are you going to recite the surah fatiha and then after fatiha do I need to recite another surah? Or only the surah fatiha?

2. Another question of mine in magrib and isha salaah on the first and second rakaat after we say ameen behind the imam, do I need to repeat the surah
fatiha silently while the imam is reciting another surah? I follow Abu Hanifa.
