I would suggest turning in your Amulet of the Lost Empire, Amulet of the Six, Blade of the Dark Six, Funerary Token, Mark of the Keeper, Signet of the Devourer, Small Wooden Idol and String of Prayer Beads. All of those are very common drops so they are easily replaced. Only Small Wooden Idol and String of Prayer Beads will you be using any time soon - the others are for recipes level 29 and up.
When you buy the Medium Collectables Bag, don't throw away the small one. Keep it in your bank for additional storage.
Edit: Have you seen the list of the 33 collectables that are used for crafting?
