Carb jetting will be based on what the plugs look like and mph at the track. Start with the standard jetting for that carb, nobody will be able to tell you what is optimal for your setup but the engine itself.
Start with the stock plugs, Autolite or I prefer the NGK's myself.
Timing will be same as jetting, start with your proposed 33 and go up or down from there, again based on how the plugs look and the cars responds.
Nitrous tuning will be at the plate itself with jets, and fine tune with fuel pressure, but I would only do that after making sure the engine tune is good.
It does need to be done in order though-
Timing first
Jetting Second
fine tune both from there once your close.
