If you have followed those instructions then you've installed three packages.
fuse_wait just replaces a single file of the NTFS-3G install with an updated version. So you don't really need to do anything to uninstall this package; when you remove NTFS-3G it should automatically remove that updated version.
To remove NTFS-3G either open the NTFS-3G preference pane and click on the Uninstall button, or run the script at
To uninstall FUSE for OS X open the FUSE for OS X system preference pane and click the Uninstall button.
If the two preference panes are still there after running both uninstalls, then just right-click on them and select the "Remove ... Preference Pane" option.
And reboot your Mac.
To confirm that the file are gone you could run the following commands in Terminal. Hopefully you shouldn't get any results.
pkgutil --pkgs | grep fuse
kextstat | grep fuse
