What is your season pass rank, and have you completed the "In the Face of Darkness" quest? The Temptation's Hook is initially unlocked through the season pass, same as the pulse rifle, and if I remember correctly, the bow is a reward from an early step in the quest. Additionally, the source descriptions on items in the collection isn't always correct. After completing "In the Face of Darkness," you'll be able to upgrade the Prismatic Recaster to allow you to focus Umbral Engrams, which will allow you to get all of the weapons you're looking for, and one of those upgrades will also make focused engrams drop shaders, which is how you get the shaders "Dark Omolon," and "Envious Touch."
