1) Uhh, long ago that I used that. From looking on what I wrote in the NBT page, I would guess something like:

The second item tag I added there is an example of a trade that lets you buy 64 vanilla stone for 10 silver coins. I didn't test if it works.

2) I believe Mevans changed this tag in one uptade to NPCName. Try that. There are a lot of changes to the NBT format over time and it's hard to keep the NBT page updated. Not that I tried, though.
