Paul's early life and mission as found in Acts, part 3

Now we will look at Paul's account of his conversion as related by the author of Acts, in Acts 22. He  is speaking to a crowd of Jews who are upset with him, in Aramaic:
-He tells them he is a Jew (Check).
-He is from Tarsus of Cilicia (Epistles- no mention, Acts  7 through 9- yes) *1
-He was brought up in Jerusalem (Epistles-no mention, Acts 7 through 9- no mention)
-He was taught the law at the feet of Gamaliel (Epistles- no mention, Acts 7 through 9-  no mention)*2
-He was zealous and persecuted the church (Epistles- yes, Acts 7 through 9- yes)
-He arrested men and women and threw them into prison ( Epistles- no, Acts 7 through 9- yes)
-He got letters from the high priest and council to go after believers in Damascus (Epistles - no, Acts 7 through 9- yes)
-On the road to Damascus a bright light flashed around him (Epistles- no, Acts 7 through 9. - yes)
-This happened at noon (Not previously mentioned)
-He fell to the ground and heard a voice (Epistles- no, Acts 7-9 yes)
-The words of the voice recorded here and in Acts 9 are basically the same. No Surprise, same author.
-Paul is blinded and led by the hand to Damascus (Epistles - no, Acts 9 - yes)
-Ananias stood beside Paul and recovered his sight. In Acts 9, he placed his hands on him. (Not in the epistles.)
-This time Ananias tells Paul his mission and orders him to be baptized "for the remission of his sins." This phrase was not used in Acts 9. Paul does not mention his baptism in Galatians. Also there is no mention here of Paul not eating and drinking for three days, as in Acts 9.
-After that he returned to Jerusalem, according to Acts 22:17, leaving out the preaching in Damascus and the narrow escape from there mentioned in Acts 9. This also eliminates the trip to Arabia found in Galatians.
-When he returned to Jerusalem, he was visited in the temple by another revelation of  Jesus, telling him to leave immediately because his testimony would not be accepted. There is no mention of the visit with only Peter and James as mentioned in Galatians. Plus there is no mention of Barnabas bringing him to the disciples and the preaching he did in Jerusalem as mentioned in Acts 9.

*1. Cilicia is mentioned in Galatians, even though Tarsus isn't. Paul supposedly travelled in that region after he left Peter and James in Jerusalem.

*2. Gamaliel is mentioned in Acts 5:33-39 as a Pharisee and teacher of the law. He was against persecuting the followers of Jesus. So why did Saul?

Also we are not told how many years after Jesus died that Saul's event occurred on the road to Damascus. If Saul grew up in Jerusalem, how is it that he never saw or heard Jesus in the flesh?
