Well, you also need LibQTip, though I suppose you could actually do away with that, since you could just do two columns with "<npc> / <item>" for incomplete quests and "<npc> / Complete" for complete ones:

	OnTooltipShow = function(tooltip)
		if not TILLERS then
			TILLERS = GetFactionInfoByID(1272)
			for i = 1, #npcs do
				local npc = npcs[i]
				npc.name = GetFactionInfoByID(npc.factionID)
			end
			sort(npcs, sortByName)
		end

		tooltip:AddDoubleLine(TILLERS, ITEMS)
		for i = 1, #npcs do
			local npc = npcs[i]
			if not npc.item then
				npc.item = GetItemInfo(npc.itemID)
			end
			if not IsQuestFlaggedCompleted(npc.questID) then
				tooltip:AddDoubleLine(npc.name, npc.item, 1, 0.8, 0.8, 1, 0.8, 0.8)
			elseif not hideComplete then
				tooltip:AddDoubleLine(npc.name, COMPLETE, 0.6, 0.8, 0.6, 0.6, 0.8, 0.6)
			end
		end
		tooltip:Show()
	end
