Plugin Request Some plugins for my new Survival RP Server

Hello everyone!

My name is James and today I am looking for a few plugins for a new Survival RP server.
I won't go into to much detail but the server will have a rank-up plugin where you kill mobs/do quests to get XP and items. Of course there will be a custom map and places people can build

Although I know/found a lot of plugins which I will need I am in need of some links to other (customizable) plugins that I am in need of.

- A customizable rank-up plugin (Preferably where you can make a auto rank up instead of having to type /rankup)

- A plugin which allows me to make custom mobs, custom loot, decide where they spawn and make them respawn.

- A customizable plugin which allows you to create quests (Preferably where you can create NPCs to give the player the quests)

And that is about it!
I look forward to your replies and I thank you in advance for any help you may assist me with.

Also it would be awesome if they can be 1.8 or run on 1.8!

Thank you once again!
