Help A Noob Out

[His Lordship]

Ok, so I've never been to Nex... but I want to use my darts.
What do I need to bring and what do I need to do?
Should I even use them on Nex?

You need to gather 4 pieces of the frozen key in each of the God Dungeons. Note that it's the rooms right before each boss room, not the dungeon when you climb into GWD. Then for the Zaros killcount you can get an ancient ceremonial set, which lets you skip the killcount and go straight into the room. As for the gear I'm not sure, but I took in medium-welfare gear and was fine.

What to wear, what to kill first, what to be wary of so I don't die, what to have in invent, should I stay longer than 4 kills?

When it gets to nex you dont actually have to wear anything because she gets 1 hit, just run in with mage prayer on and dart wielded. If you do somehow die then dart gets saved automatically anyway.
There is a bank before the nex room. The part that wastes time is getting the Frozen Key which Al has explained above.
