Searching for 2 plugins. Login plugin and different money per world.

Hello!
So, I started a server with friend and it's very cool, but I cannot find some plugins.

1) Login plugin
So, I need a plugin that logins players automatically if they have premium account and others, who have cracked will need to register and login after that if they join again and they wouldn't be able to login in premium members accounts. Is that possible? I was reading about FastLogin and I couldn't try it because it didn't even let me in the server. Message was something like "Server is not loaded yet" - something like that.
So, do you have any ideas about plugin like that?

2) I am also trying to add different money values per world and I didn't find any way for that. I have plugins like Multiverse, InventoryPerWorld, Essentials and others which aren't really connected with economy.
I tryied mvmoney (multi world money) but it wasn't even working for me. Nor commands. Also, any ideas about that?

Wizertex, thank you very much for your answers!
