First off, interesting to note that you did not ask of proof of the other two.

Somebody married and banged a six/nine year old? No problem. Somebody took his adopted son's wife? No problem. Character still noble.

It is the "bite your father's ****" statement that you want to see proof of? Anyway no problem here you go,

Al-Adab Al-Mufrad 963
'Utayy ibn Damura said, "I saw with Ubay a man who was attributing himself (in lineage) with an attribution of Jahiliyyah, so Ubay told him to bite his father's male organ and did not speak figuratively (i.e. was explicit). So his companions looked at him. He said, 'It appears that you disapprove of it.' Then he said, 'I will never show apprehension to anyone with regards to this. Verily, I heard the Prophet, may Allah bless him and grant him peace, say, "Whomever attributes himself (in lineage) with an attribution of Jahiliyyah, then tell him to bite his father's male organ and do not speak figuratively (i.e. be explicit)." ' "
