Teleport NPCs & Custom Vendors

Okay so basically i want to make some teleport NPCs and Custom Vendors or vendors for specific classes with gear and stuff. I've had a look at a few guides and im just confused because people leave bits out and im new to the whole private server thing.

So how would i got about doing these things, i've heard of people talking about using lua scrips and other more confusing ways so im not sure what to do or how.

Im running the Lbniese-Repack 2.9 (3.3.5 patch) Arcemu thing. Extra information i have got the server up and running publicly and have used HeidiSQL to make accounts and custom weapons.

Any help is very appreciated!

Thanks for your time,
Dave

EDIT: found a great thread on the forum for a teleport npc called Multi NPC works fantastic so i just need to sort out getting normal vendors/custom class ones.

go on WoW-V.com and sign up and click create and u can make custom vendors items etc.
