Restoring data from iPad to new Mac after old Mac died
Your personal, i.e. non-purchased, media can be copied from your iOS device using Macroplant's iExplorer.

If you could mount the iOS device's filesystem directly, you could find your media in Media/iTunes_Control/iTunes—if you had a Linux system handy, for example; I don't know of a way to do this directly on OS X.  The files stored in that area are renamed seemingly randomly, but should be able to be imported into iTunes since their media tags should be intact.
