You can install gnome-terminal for Terminal, nautilus-wallpaper for Set as Wallpaper, nautilus-gksu for Open as Administration, nautilus-terminal for Open in Terminal option. All of this can be done in Synaptic.
You can also install nautilus-actions and nautilus-sendto, or even nautilus-dropbox, nautilus-flickr-upload... They are not installed by default but they are quite interesting.
It is quite easy to understand because Cinnamon is just a "shell" for GNOME 3, therefore it has full Nautilus.
