2. Recipes are items just like scrolls, you can buy some from an NPC, but most are dropped from monsters.
3. Although the previous question is true, I'll answer it nonetheless: it depends on de recipe. With most recipes you can only get 1 try (so if you fail the crafting you lose the recipe), except Alchemy recipes which have a time limit of 24 hours. There are also recipes where you can make unlimited equips, but most of them are for lower level equips.
