[OANST]

A list of all the scavenger hunt items is a bit much. It tells you how many are in each area when you are in that area. That makes it a little easier. The first lungfish vault is through the tunnel of lasers. I believe the other one is only a little ways in front of the first prison. As for the milkman, make sure that used the first set of telephone wires as well as the second. The first leads to a tiny island with a slide. If you haven't done that one then it is probably what you are missing.
