Regarding listing the crafting ingrediants:
The player looks at the recipe list and the various item names are all colored. If they have no ingrediants to make that item then the item name is dull, if they have some but not all then the name is displayed in some color like white. If they have all of the necessary ingrediants then the item name is a bold green color. That would make it easy to locate things they can craft or need more stuff to make.
Then, selecting any item from the list displays the items in the crafting menu and then dulled-out pictures of the ingredients are shown in the materials slots. These similarly have are colored with dull grey being absent, white being you have the item, and then if you drag and drop the right ingredient to the slot then it shows a colored picture of the material.
Basically, take a look at the Team Fortress 2 crafting system where any time you have to craft an item the crafting menu will show a dulled-out picture of it in the slot where you will eventually have to put it.
