Finished up installing the shift kit yesterday. The 4th gear accumulator also had a sonnax pinless accumulator in it, but the servo was a standard smaller truck servo, so I put a larger "Corvette" one on. I couldn't see, or know well enough, to tell if it had any upgrades internally to the drum or sun shell. Overall, everything inside looked about as expected. I'll have about $275 into this transmission (including the cost of the transmission and the accumulators I ended up not needing), so if it doesn't work I'll backup and get a full rebuild kit.
I also finally plunked down the cash and bought a turbo kit. I didn't get the "perfect" size I'd get if money were no object, but went with the turbo kit the Sloppy Mechanic's guys use for the 4.8L LS's. They're making 600HP with them, so figure the HP figure is about right. It's a 69mm inducer wheel and appears to have a 1.05 A/R. Hopefully I know more when it arrives.
