NOTE!
In order to install future updates, the March 2013 PU will be mandatory!
So you must install these updates on RTM Farms before you can install subsequent updates in the future!  (http://blogs.technet.com/b/steve_chen/archive/2013/03/22/3560441.aspx)

As usual, you need to run the SharePoint 2013 Products Configuration Wizard on each machine in the farm after installing the packages.

The SharePoint Server pack contains the Foundation packs, so you basically only need to install one Package.
The project Server Packs are containing both, so if you install this one, no need for the other two to install additionally.
