MCEdit allows you to copy chests full of stuff over from one world to another pretty easily, from what I've heard, probably with less work than it would take for you to go into the game in creative mode and spawn stuff for people. Might wanna look into that if the clamor for item transfer is high.

I'm cool with just doing a complete reset with no item restoration though. I might even run with the fresh start thing even if other people ask for items to be restored, actually.
