So where are you going with this thread? The evidence, as I see it, is conclusive that the bible, including the gospels, has been repeatedly edited and redacted. This is an obstacle to acquiring faith and hope from these scriptures, but not an insurmountable one. Just because a text has been tampered with doesn't mean it should be entirely discredited. The questions should be asked, however, why these changes have been made? and what conception of the those scriptures has resulted from those changes? Though I see the importance of researching scholarly analysis of texts to discover which words stylistically clash with the context of other words, it is also important to approach scripture with one's own living sense of spirituality, faith, to discover which words are in harmony with what one discovers in one's own spiritual life. As for Jesus singing a psalm to himself on the cross, it could be as simple as how any slave would have sang himself a spiritual while being whipped. I don't see much point in looking for the fulfillment of prophecies. Prophecy and psalms are concerned with the here and now, the always moving present. What I do see in both psalm 22 and in Jesus' life is that some people, perhaps all people, have a calling to fulfill. Often, it seems, the most meaningful callings involve the most suffering. I do believe that Jesus was called to live a divine life, and to teach the world about divinity and how humanity should live. The alternate translation above does give a different slant to the singing of this psalm. Either way, though, the recital of this psalm on the cross need not mean that Jesus was exasperated with his fate, it could simply be that the psalm came to his mind and seemed appropriate to his situation at the moment as he bled from the nine inch nails in his wrists.
