Hi

Yes, you should install to versions of Oracle client.
Check this: http://resources.arcgis.com/en/help/main/10.2/002n/002n00000038000000.htm for setting the two clients for desktop and server

Have Fun

Yes, in fact that is what is required if you install ArcGIS for Server and ArcGIS for Desktop on the same machine as you are doing.  If both ArcGIS for Server and ArcGIS for Desktop are installed on the same MS Windows machine, specify the 64-bit client before the 32-bit client in the PATH environment variable.  Otherwise, you will experience connectivity issues.
