This is really not something to be answered in a simple forum thread. What you are asking for is pretty much "how do I configure all of OM/PD?".....which is far more involved than this forum space allows....and I would be very suspect of anyone giving you advice a such ("here are 10 steps and you will be done!") here as well. I would follow through SAP's configuration documentation (help.sap.com as well as IMG docs) and other material. You can/should even get the SAP Press book on OM by Sylvia Chaudoir (Mastering SAP ERP HCM Organizational Management).
If you have specific questions about specific aspects of OM, then this place is better suited for those.
