Need help with dayz_code editing

[-SFWS-Hawk 0]

Needing help with customizing my DayZ server.  I've been playing on a server that has slow zombies, self bloodbags, suicide, and always daylight.  I want to do a similar thing with my server.  I have found many posts on other websites about where to edit and none actually are working.  If someone could show me step by step exactly how to accomplish this, that would be great.  And also how to add god mode to trader cities and no backpack theft. Already finally customized the starting loadout.
