p represents the no. of the ring being considered as there are many rings. SO, p=1 means the 1st dark ring and so on.
Also the path difference of the interfering waves of light at the p'th dark ring is p .

No. Do not do diffraction pattern. But newton's ring is an instance of interference, I think you should atleast go through it a couple of times. because it can come as a Passage question under intereference topic.
