Effects Noob building a pedal board and need advice

Hey guys...complete effect noob, but interested in building a pedal board and trying some different effects to see what will fit my current gig. I play in a CCM/Southern Rock style group. I have a few pedals I am going to mount on a pedal board and though I would check out and see what type of effects I should look into that may fit that style. I currently have a navigator foot controller and a Korg Pitchblack that will mounted. I have thought about adding a chorus of some sort....anything else out there I am not aware of that could be useful in a southern rock type of band? Thanks in advance

 

Thanks!
