Usually with nitrous you aim to tune the motor as optimal as possible on fuel alone first. This helps to balance air-fuel ratios and help deter detonation. Nitrous does nothing but benefit an already tuned motor.
Usually with nitrous you slightly lean a motor out by jetting the carb correctly with the recommended jets and retard the timing to account for the increased combustion efficiency. From there it is a matter of simply tuning the motor for each individual build to find the sweet spot.

This is really too general of a question.
I would suggest going to www.thirdgen.org and do LOTS of reading. You will learn much more than here. Nitrous is safe if you know how to tune it.
I will start with some basics.
Decide on how big of shot of dope you want to run. Also figure in it won't be enough and you will want to go faster.
Build your bottom end accordingly especially your pistons.
Make sure you gap your rings correctly for nitrous. This is especially important if you run Keith Black pistons.
Unless you run some sort of digital timing box you will have to manually retard the timing when you spray. A general rule of thumb is retard 2 degrees for every 50hp.
Make sure you select the correct spark plugs.
Get a WB and learn how to read spark plugs if you get serious.
Make sure your fuel system is up to the task of adding the extra fuel or run a separate dedicated line for the fuel solenoid.
Nitrous has a bad rap because people just throw it on their cars and wonder why it blows up.
Best of luck.
