And how does one get baptized by the Holy Spirit? Does it simply mean receiving the Holy Spirit, or is it something more like sanctification? I'm looking for a scriptural answer, not a fuddy duddy conservative answer or a charismatic answer. 
Here are some refs - are these at all related?
Mark 1:8
I indeed baptized you with water, but He will baptize you with the Holy Spirit.
Luke 11:13
If you then, being evil, know how to give good gifts to your children, how much more will your heavenly Father give the Holy Spirit to those who ask Him!”
John 20:22
And when He had said this, He breathed on them, and said to them, “Receive the Holy Spirit."
(They didn't have the Holy Spirit before this?)
Acts 8:12 But when they believed Philip as he preached the things concerning the kingdom of God and the name of Jesus Christ, both men and women were baptized. 13 Then Simon himself also believed; and when he was baptized he continued with Philip, and was amazed, seeing the miracles and signs which were done. 14 Now when the apostles who were at Jerusalem heard that Samaria had received the word of God, they sent Peter and John to them, 15 who, when they had come down, prayed for them that they might receive the Holy Spirit. 16 For as yet He had fallen upon none of them. They had only been baptized in the name of the Lord Jesus. 17 Then they laid hands on them, and they received the Holy Spirit.
(This last one is really confusing to me. What did it mean that they had believed and received the word of God? Were they saved yet didn't have the Holy Spirit?)
