I think I'm the only person here who actually talked to the refugees and visited their camp every day, not to mention found the stuff on my own (more of a pride thing xD)!
PS: the items locations are hinted heavily in the NPC dialogues.
I couldn't be online every day, but when I was, I did visit the refugee camps
A comment though, the item locations aren't so hinted, because they change from day to day while comments stay the same. For example, when I got the first snow covered item it was in the north, but next day someone asked in chat and directed them there... yet it wasn't there anymore, so we searched for half a map and found it near maw, on the other side of the zone almost.

Also, it would have been helpful if you'd showed what items you turn in to which NPCs, that would've helped me narrow it down too. >_<
Edit: Finally found it after running around Wayfarer 2x.
You can talk to the named refugees in Lion's Arch. If they're missing an item their speech will be about that. Once you get them their items, their speeches change to talking about the war and losing family and all that.
