Afterwards I configured the workstation and router IP address information.  Finally, tested connectivity using the Ping command. 

This topology (using only straight-through cable and FastEthernet ports). 

Router was configured by going to router and clicking the config tab. On this tab you can change the Display Name and Hostname of the router.
