Unfortunately, there is no way to increase your Item Discovery through levelling up Vitality, Endurance, etc. However, it can be increased through the use of:
 * 1) the Covetous Gold Serpent Ring
 * 2) the Symbol of Avarice
 * 3) humanity

Also, as far as I know, upgrading armour pieces shouldn't affect your Item Discovery at all.
