Answer 1

I don't yet as I am still playing and haven't reached them, but this document will tell you :

I know, however, that you cannot get the Zodiac Spear if you have opened any of the following treasure chests (which I think is supremely ridiculous on Square/Enix's part...because I found that out after having opened them!!) :

Treasure chest in front of Dalan House, Lowtown Rabanastre.
Chests in Rabanastre palace; South east corner of the cellars
Cests inside Nalbina Dungeon in the room where you get your inventory back
And finally, the 16 chests in the south east area of Phon Coast

Answer 2

The genji gear must be stolen from the hunt that makes you fight with gilgamesh and they can only be stolen at certain times that zodiac spear you get in the necrol of nabudis but only if you didn't open certain chest throughout the game and that's all I know I didn't really try to get all the best weapons yet so cant help there but gamefaqs.com would know where everything else is.
