If you have the older, separate Fortran then it has an uninstaller script that lists all files - it should be in /usr/local/bin/gfortran-uninstall or you can consult pkgutils (see below).

No, Apple has made no changed to gcc for a while since they stopped using it, so you can safely use it with any recent Xcode 3.2.x version. You don't have to use it, but for SL it is recommended. Don't forget to run "sudo gfortran-uninstall" before you do so you don't have two different Fortran compilers on your machine - just to save some trouble.
