FFIV Weapon Armor Collection (SNES)

Well, im considering obtaining one-of-every weapon and armor for completions sake. ive noticed no ones really done a 100% faq for this game, so im guessing maybe you cant. I realize the insanity of this endeavour, primarily the Pink Tail, so spare your comments.

First of all, im talking about the SNES version.

Anyway, a few questions regarding this matter:
Is it possible to store one of every Weapon and Armor in the game? Does anyone know how much item slots the fat chocobo posesses?
Any rare enemy drops which are obtainable in the once-only dungeons?
How many 1 in 64 drops am i looking at here roughly?

Any tips or advice for this gargantuan task is greatly appreciated. Especially from someone whos actually done it.

I find it hard to believe that no one has any Help, whatsoever.

... and you call yourselves final fantasy fans!

You can't because you relinquish the Legend Sword for the Excalibur.

Unless you cheat. :D
