I believe you will only get the individual installers when you purchase an update on DVD. Since you are getting the 2013 EverythingPAK, assuming you want to install to your local hard drive, the installer actually just does a "copy" of all the files from the USB drive to your hard drive. So yes, it is a one step process. You could even do it manually, if you wanted to; however, the installer also installs the necessary fonts, the DX effects, etc.
So once you tell it to install, go get a cup of coffee and read the newspaper while it's doing it's thing.
