Reinstalling GarageBand

I clean installed OSX 10.9.4 on my Macbook Pro Retina. I was adding my applications back from my time machine backups, and when opening GarageBand it immediately began downloading the essential collection of sounds and loops. Where within my Time Machine are the sounds and loops already stored, so I can avoid the hour wait time of having them re-download from the internet? I also Purchased the additional drummer and synth package, and would like to add them back to the application without downloading or paying for them again.
