You're not asking anything that hasn't been asked already!
Lots of us would like to know more, and have tried to ellicit more info from folks that've done upgrades. Either they people don't come back, or they didn't do the work themselves and the shop they used isn't giving up the info, or this, or that, or you get the idea...
Adam has a nice VFAQ on his dfwsbr.com web site. But even it doesn't answer all the questions.
Try doing a bit more exhaustive search through the Technical portion of the board, you really can find answers to a LOT of your questions. There are even some posts somewhere where people put up the circuit diagrams of the whole system. I have that somewhere, if I can find it I'll put it on a web site a drop a URL in here.
