You don't actually need the magazine, just the ingredients, though the magazine does tell you what the ingredients are, so they are super useful if you're not bothering with a guide.

Also, Ray Bomb is one of the hardest Blue Magic spells to get for Quistis, because it's a rare item that only drops from a certain enemy when they are a certain level. So if you happen to be poorly leveled, you'll need the Lv. Up/Down abilities and some scan spells to finally get it.
