There are thousands of files that are part of the Xcode installation. One thing 
you can do to identify them is if you still have the Xcode 3.2.6 installer 
package, open it. On Mountain Lion there were numerous complaints when I did 
this, including that the installer had to relaunch, that the package's 
certificate had expired, and that the package had to run a program, but after 
acknowledging all three, you can select Show Files from the Installer's File 
menu and turn the disclosure triangle next to each of the packages to see what 
files they install. You can then check your hard drive to see if any of those 
items still remain, and manually remove them. Note that while the files in the 
System Tools and UNIX Development packages are shown with paths relative to the 
root of your hard drive, the files in the Essentials package are relative to 
the /Developer directory.

Some of the files listed are still part of the current version of Xcode, 
particularly when you install the command line tools. So after manually 
removing Xcode 3.2's old files as above, you should (re)install the command 
line tools of the current version of Xcode.
