not all of them, if you check all the gear:
craft pants +15 craftsmanship (you can survive w/o but with it you can use another piece of gear for more M craftsmanship)
the 3 shield (grid got the best block rate of 168 or so while Uldah got the best dmg reduce and the LL is both and give +10 atk power)
2 rings
Chocobo gear at 1.21 (useless, but they will be decent at 2.0 and you cant craft them, only buy from GC)
end of the line: look at the vision the game is heading
edit : forgot the shield at grid as well +10 m accuracy, decent for THM
