Questions for you guys running THM 400s

Guys, I'm putting a turbo 400 in my project car and I have a few (hopefully simple) questions that I need to figure out before I begin.

Is the stock GN driveshaft the right length? If not specs please...
Can you use the 2004r tranny cooler lines?
Do you use the vacuum modulator and if so how do you plumb it and prevent putting boost into it?

Any other tips on this conversion appreciated.

Oh yah, I don't want to do the manual valve body or transbrake thing (yet). I just want it to function like a regular 3 speed tranny on the street for now.
