where are the iTunes plist files

I changed to Lion. Because the OS I started from had corrupt files I opted to partition and create a clean instal. Because of the corruption on the old system I do not want to use file migration. The only two things I need to move are my .plist files for iTunes and iPhoto, which I can find on the old system but not on Lion.

I unlocked the hidden files but I can't find the library or the prefernce folder in which to place the old .plist files. Where is it? Does anyone know?
