Generally speaking, you would want to retard your timing to 10 degrees initial with your kit, while still burning premium fuel to keep detonation under control. Your intructions, with your kit, should give you the specifics of this. Your fuel pressure should be set in accordance with the size jets you are using, as well as what pressure your system is supposed to remain at. If you do not have a bottle heater, I would recommend you save up for one. Systems without heaters see huge fluctuations in bottle pressure, which leads to inconsistent performance. Good luck!
I'll leave this to the big tuner boys... but since it is a free world to type...
If you currently have your timing retarded for whatever reason, you should pull from where it currently is. Advancing back to stock and then pulling from there would only seem to leave you unprotected from your original issue (bad pump gas maybe) that you retarded for. Right?
The NOS isn't going to build you any buffer to help compenstate for your orignal retard, it needs it's own buffer so I think you should retard 2 degrees for every 50 shot on top of whatever retard you may already have. That would be the safe route anyway. Then as you balls mature and begin to drop, you can try to put your timing back in!
Seriously though, call the NOS tech support line. 3 years ago when I had NOS, I called them and they friggin' answered the phone and had all sorts of information for me. They were pretty awesome back then, maybe they still are today.

I am always more conservative than necessary but maybe that is why I have (well had) a 11 second 120,000 mile plus stock block AOD car. Here is what I would suggest. 1 or 2 degrees cooler heat range on the plugs and 2* retard for every 50 hp shot. Begin there. Then you can either tune based on reading the plugs, or if it were me, spend the $150 bucks and get it on a dyno and tune the thing there using the wide-band O2.
Start conservative and then work your way up. Be patient and you'll be a bottle freak in no time.
Take care...
