Answered your question already ingame, but doin it here also for all others.
You dont need Fire Res Gear.
*Except 1 Fight: 4HM in Naxx and its also depending on your guilds tactic.*
Thane Korth'azz - Meteor
14250-15750 fire damage, share between all people within 8 yards from the center the meteor drops. Cooldown is 12 secs. Random target in ~ 20 yards. Players will have to stack up when fighting Thane Korth'azz to avoid having the full damage piled upon one person.
You either stack up more people or some go in with FireRes, which would lower the DPS ofc and its less likely this tactic will take place on Nostalrius, since most guilds running into Naxx, have enough experience.
Which will lead again to:
You dont need Fire Res Gear.
