What configuration files do I need to copy over so I do not have to rebuild all the configurations?
You need to browse to C:\Program Files\SSC\RRR\, and copy the file RRR32.ini. The other file you need to copy is located in C:\Documents and Settings\[current user]\Local Settings\Application Data\Scott Studios\RRR. The file to copy is schedules.xml. By installing RRR on the new computer, and copying over those two configuration files, you will be able to use RRR on the new system without having to re-enter any configurations.
