Recovering Compressor 3 & settings from old CLONED drive?

I was foolishly on a late night mission to find a better, faster way to compress my FCPX mov files, so I installed Compressor 4 to check it out. Amidst the mayhem, I accidentally deleted my Compressor3 application, which was housed in application bar. I'm freaking out realizing I did this the other night, as I had my old version of Compressor saved with all my custom presets and Qmaster configured to cluster render using all my available processing cores.

Now here might possibly be my saving grace; I have a backed up CLONE external drive which has all the old stuff and files on it. Is there a way to drag and drop not only the old Compressor3 but all the settings associated with it too back onto my current HD? Will I need some sort of .apple.compressorplist files or anything crazy like that??? Any help would be greatly appreciated! Thanks in advance guys.
