1) Refers to a physical pin in the netlist. Terminals and vias do not count towards your limit! 2) Standard (Level 1) power planes must cover and entire layer (board edge to edge) and cut-outs are not allowed. 3) Provides a standard "design file out / session file in" interface for most common external autorouters.
