NOI is notification of interest, issued by provinces inviting you to live and work there. If you accept NOI, you will pay 1500CAD and submit the required documents with Provincial authority. If everything goes well, province will nominate you and awrd you 600 points. Then you will have 1000+ points and receive the ITA from CIC. The same procedure applies after receiving ITA.
PNP is paper-based sytem, and I am sorry I don't know much about it. A friend applied for PNP 2 year ago, and as far as I know, the process is really slow. He hasn't even been asked to do medical yet.
