Actually you are about 4 weeks late on the turbo
Couple other notes:
I highly recommend running a single Walbro 465 (or whatever they call it now...p/n ending in 267) with a front mounted regulator and return line. My fuel pressure is much more stable and it can be pieced together pretty cheaply and easily and it will support more power than your LS1 on 93 octane. I can send more details including p/ns if you are interested.
I also highly recommend going with a ZR1 3 bar map right from the start. It's actually cheaper than the cobalt 2 bar map and much more accurate than other 3 bar maps. It wasn't an option for LS1's until recently but HPtuners now allows for negative offsets to be programmed in.
Only other advice I can think of off hand is to use a decent valve spring ( Brian Tooley duals, etc) and the trunion upgrade for stock rockers. I'm sure there's a lot more so just send me a pm
