Sounds like a great project

Why do you want to go with a 9inch? If I knew back then what I do now, I would have gone with a Moser 12bolt with Ford-style ends and 33-spline axles. I'd still be running a TrueTrac either way though.

1) Your axle choices for a performance 9" are 31-spline or 35-spline. Your only differential choices for 35-spline axles are Detroit Locker or a Spool, both of which suck for anything but driving in a straight line--don't even think about trying to turn into a parking spot with a spool. For the 12bolt, you can get 33-splines axles and just about any differential you want. I want a TrueTrac, so I could have gotten stronger axles with the 12bolt.
2) The 12bolt weighs a little less
3) The 12bolt takes a little less power to turn
4) I have no plans to swap out center sections to change gears, so that's not an advantage to me.
5) price is a wash I think between a 31-spline 9bolt and a 33-spline 12bolt

There has been a ton of discussion on this over in the Tranmission & Driveline forum on camaros.net.
