I've done my best to try to understand how the attack power works, but I may be wrong. Either way, this definitely shows how strong a weapon is compared to another one. If you see the word "Item:" in the Effects field, the word following it is what spell is activated if you use the weapon as an item in battle (select Item, press left, and press A twice on the weapon you wish to use).
Prices mentioned are the selling prices. Buying prices are usually double that price. If buying in bulk, buying prices can be lessened (10% discount for 4 at a time, 20% discount for 10 at a time).
