There may be better ways of doing this, but you could:
For pictures, install Google Picassa, get it to scan your whole computer for pictures. The program has a 'find duplicates' faclility under Tools>Experimental. Not sure how good this is, but its a start I suppose.
For music, install Itunes, get it so scan your whole computer for music files. Itunes has a tool called 'consolidate library'. What this will do is MOVE all your mp3's which are dotted all over your PC into a single folder, and file them under Artist>Album (if your music is correctly tagged, or it can find the information online). This will make it much easier to backup. The location of this folder can be chosen by you under 'Preferences' in iTunes. Then you can get Itunes to list duplicate files in your library, which makes it easier to delete duplicates.
