I work as a reverse engineer processing point data all day long. Also a newby to CNC. I have found with the software available today, work directly from scan data. The file format is .stl from most scanners, and Rhino, meshcam, and vectic software will generate tool paths directly from this data. The scanner you mentioned seems OK, but there are service companies that will scan your part and work the data into a closed solid.
Hope this helps.
