mac, I'll put the first three items on a vendor at margrette's shop in zento in a little bit.
Edited to add: The stuff is on a Special Orders vendor at my house just off the NE corner of the wall around Zento. I wasn't quite sure what you meant by "barrels," so there are some liquor barrels, metal kegs, and plain old wooden kegs (not potion kegs) on there.
