Launch nautilus with gksudo:

gksudo nautilus

Create a file names nautilus_root.desktop in ~/Desktop with the following contents to create a desktop shortcut:

[Desktop Entry]
Version=1.0
Encoding=UTF-8
Name=nautilus as root
Comment=Launch nautilus as root user
Icon=system-file-manager
Exec=gksudo nautilus
Type=Application
Terminal=false
StartupNotify=true
NoDisplay=true

You can use gksu to wrap su and sudo calls.
