I like to know exactly what files an application installs on my system so that if I later decide to remove it, I can do so cleanly. In fact, this is one reason why I prefer Macs to PCs, because I don't have to mess around with regedit every time I want to fully remove an app from my system. Anyway, Little Snitch is unlike most Mac apps in that it installs files in a number of different places on your system. From what I understand, the uninstaller does not completely remove all of these files from your system, either -- leading to potentially unpleasant unintended consequences.
Below I have compiled a list of every file that Little Snitch 2.0.3 has installed on my system. Perhaps it will be useful to those of you who want to fully remove the program while you investigate anomalies with your system. While I believe the list to be complete, if anyone discovers other files I have missed, please post a followup with the path to the file.
Note that lines ending with a '/' represent directories that contain one or more files which are only part of Little Snitch. Note further that the '~' symbol represents your home directory. Finally, note that the directory marked with '(*)' contains the Little Snitch registration files, including a hidden file (.lsd) that will not show up in a Finder window. Removing this directory will, however, remove all traces of your registration from your system.

With regard to the need for Sophos, see my Mac Malware Guide. There is Mac malware out there, and Sophos will protect you against it quite well, but Mac OS X does a pretty good job itself as well. One class of borderline malware - called adware - is becoming increasingly common, but most of it is not blocked by either Sophos or Mac OS X, unfortunately. Thus it's more important to know how to protect yourself.
