Have someone cap lights and if the timed Nms are up do the NMs while someone else farms pops for the pop NMs, if Min/Adze are down AoE farm for KI. You're going to wind up with a variety of Chloris KI if you just gold chest farm; if that's fine with you and you don't care to proc on NMs stick to gold chest farming. A mixture of both is the fastest method.

IF no one else is there you should be able to brew multiple but if others are around I wouldn't trust them ever. As for brewing we only brewed ~4 and he 2houred mid brew every time; if he switches to magic immunity during Blood Weapon then he's going to take longer to kill wasting brew time.

We used the martello but yes you can lock brew assuming you didn't waste too much time killing him.

We killed him WHM WAR NIN THF + extra (friend on Mnk or Sam depending, he didn't have any better jobs at the time), he really isn't that hard whether you stun gorge/disgorge or not (unless really unlucky with a 3k+ Disgorge from no Gorge), as long as he didn't switch to weapon immunity constantly during 2hour (far too often for my tastes) he dies fairly quickly, bring a BLM/SCH/SMN if you're that worried about that.
