Plugin Help First time setting up a server. Please help! ^-^

Okay, so far I have these plugins:

Essentials, WorldEdit, WorldGuard, PermissionsEX, HeroChat, CreeperHeal, anf Gringotts. (Later I will add PortableTent, McMMO, CrackShot, and possibly a few others, but I want to start off with just the basics) Also, I read that some of the other plugins (Such as worldguard, gringotts, herochat, and PEX do the same things that some of the parts of Essentials do. Should I remove those parts of essentials? If so, how exactly?

First time starting up, I recieved a few errors. Here's my log:
