[Nessful]

Hello guys. I really need some help. What i want to do is give everyone that logs into my server a starter item, like the Binden Concerrtia * ports to nexus * then i would like to add my OWN merchants in nexus, and my own npcs. How do i add my own merchants and npcs? Also another quick question, how would i create a new mob as a regular spawn mob, like, how would i put a mob named The sleepers father in the sleepers tomb?

Note: I have all of GeorgeS tools i just need help please.
