Ok, every server just needs Essentials. Also, towny is very useful, as well as WorldEdit, PropertyGuard, etc. For the bank and stuff, use Vault. For the religion, God's Plugin. Thats all the plugins. If it's gunna be a modded and Bukkit/Spigot server get all those plugins for Bukkit/Spigot but mods, McCrayFish's furniture mod, and the car mod. Have fun with your new server!
