I would LOVE to help you with this, but it goes WAY beyond the primary purpose of a forum post - that being short, targeted, straight-forward assistance. What you have isn't any of those.

My best advice is to get a really sharp performance tuning professional on board for a review. There are some good ones on this forum and elsewhere. Perhaps someone else will decide to jump in on their free time and try to help you out with this one. Best of luck!
