Alright, I think I'll work on some NA OT templates over the next few weeks and post them here. I need to make sure it's legible, coherent, and - most importantly - credit is given where it's due.

Glowing... star? Materials that have either a white or a red exclamation point (in the upper-left, I believe) are necessary for quests. Most everything else can be sold, unless you want to keep an old weapon or piece of armor for some reason. Often, materials/items that don't have an exclamation point will be used for future quests; the white exclamation point merely points out that you've seen a Monado vision telling you the item is necessary.
The vast majority of items in the game can be gotten as drops, and the drop rate even for rare items isn't nearly as brutal as it can be in some RPGs.
