AI Limit has a total of 21 headgear and 18 armor items to collect. Headgear and armor are purchased from shops, obtained from the environment, or after defeating bosses or specific unique enemies. Collecting these is not required for any trophy/achievement, but they can increase your survivability in the various areas or against bosses.
Headgear and armor can be sold to shops without penalty, but there is no way to obtain them again in your current playthrough, so be careful selling any before NG+ where you can pick up duplicates. The majority only sell for a few hundred Crystals, so it is better overall just to keep one of each.
The most useful set overall is the Clergy set, which you obtain automatically after defeating the main story boss Saint in the third area of the game. This is because it has the highest overall ELECTRICITY defense. Almost all Church enemies deal electricity damage, including all bosses in the final two areas of the game. Other sets are slightly better for specific bosses, but you can spend most of the game using the Clergy set if you wish.
