AOA ya akhi
My brother as far as the length and style of the beared is concerned, i haven't read anything in the bukhari or haven't heard from any scholar about it. All that i know is :
Saheeh Al-Bukhari
Volume 7, Book 72, Number 781:
Narrated Ibn 'Umar:
Allah's Apostle said, "Cut the moustaches short and leave the beard (as it is)."
Inshallah that should answer your question.
