There's one MAJOR thing you need to add to a Windows8 system, and that's Classic Shell (http://www.classicshell.net). It brings back a sane desktop (as far as anything on Windows could be considered sane), with the start menu and all. It also sets your system to automatically bypass the formerly-known-as-Metro interface. Once you've done that, you can start adding your Firefox, Thunderbird, LibreOffice, VLC, InfraRecorder, and so on.
