Here is my opinion
Necklaces: Good for another job, Craft them using pearls, gold, diamonds etc and sell them if you like. Have about 5 or 6 different kinds
Wings: I don't know how to produce these...
Backpack: Good idea to pay for them, but let them have certain attributes (with a backpack you can hold maybe 5 bottles for milk, not three)
