I hope all is well. Mike was out of the office on Friday, and may not respond to you till he returns, so I thought that I would quickly jump in and answer you in the mean time. The highlighted area above that you are asking about is what Mike was referring to.
DO NOT use the link in the highlighted area to do the post-configuration of WSUS, or you will break the WSUS / SCCM integration and it will not function correctly.
As Mike was indicating, the remaining configuration of WSUS will be done from within the SCCM management interface.
You can go and take a look at the shows in the library that I did on "System Center 2012 Configuration Manager - 70-243" I walk through the complete installation, setup, configuration and management through update deployment of the WSUS and SCCM integration.
Look for the episodes under the title "Deploy applications and software updates".
Please let us know if you have any other questions. Good Luck !!!
