Deploy Office 2013 with language pack

Hi,

We want to deploy Office 2013, for this I followed the tutorial: http://gallery.technet.microsoft.com/office/How-to-Deploying-Office-0f954e7f

In the first step I need to make an MSP file, but this file doesn't get used in the deployment? I think this is a fault in the tutorial.
Also the uninstall string is setuP.exe /uninstall. Is this correct?

Second we want to deploy the dutch language pack with SCCM 2012, but I can't find out how. The package need to be installed but Office 2013 still need to be default language English.

Can someone help me out with this?

Thanks in advance.
