Do a search on S-Series.org
I remember helping one guy extensively with it there.

Basically... Yes, the timing should be at 0* with wire under dash unplugged.
Use the large notch near the bottom of the timing mark tab, that is 0
The rotor should be pointing to the front slightly to the drivers side when #1 piston is at TDC. Also this is where #1 plug wire goes and they follow around clockwise 1,6,5,4,3,2 (4,3 to the rear)
On my GT I have found that 2* - 4* base advance actually runs better but I also have vortec/header upgrades so it may not apply to yours. Eventually I'll get this corrected in the tune when I get into programming.

That should be all you need to know to get your SoGT timed correctly. If it's still running rough, double check your plug wires and plugs. Then it may be another issue.

Oh yea...
After all of that, turnoff the truck and plug the wire back in.
Disconnect the battery for a minute or so and reconnect.
Drive the truck around town a bit to get it up to opperating temp and turn it off.
Restart and do it again just to give the ECM plenty of time to learn again.
Check for codes by jumping the ALDL plug.
