I am new to mapping and not familiar with the acronyms and standards. With that said I am trying to answer the following question:

Geographic point locations used in the Solution should be displayed in an industry acceptable G.I.S format; does OpenStreetMap maps use geographic coordinate system (Latitude, Longitude) with a North American Datum 1983 (NAD 83) and not NAD 83 (CSRS).

Any help is much appreciated.

OpenStreetMap data is stored is stored and distributed with unprojected WGS84 coordinates EPSG:4326. Typical maps displayed on the web use googles web mercator EPSG:3857, the maps displayed on openstreetmap.org are no exception to that (see EPSG:3857).

But naturally you can project OSM data to whatever you want for display purposes, however I'm not aware of a tool that does it directly (typically you would convert to shapefiles and reproject those).

You can actually reproject OSM data when uploading it to PostGIS with osm2pgsq, which is a suitable way of consuming OSM data for a wide range of uses.
