A good list of ideas but a note on projections:
        "b) different between a few of the popular projections such as UTM
v/s State Plane and their properties and zones."
 
State plane and UTM are NOT projections, they are co-ordinate systems. Each
(and each state) have an associated projection. Thus the associated
projection for the UTM co-ordinate referencing system is one of many
transverse mercator projections (zone such-and-such) unless of course it is
in the far north or south. We use a conic state plane projection here in
Montana because of the east-west orientation of the state.
