Sorry for the noob question, Everyone in the crypto world assumes everyone can program 

I am getting my first KNC unit soon, I am not used to IP mining, Is it really as "plug and play" as I assume?

As far as I can tell, I look up the IP of the unit via my router,  put this in my browser, and click on mining and put in my pool details directly, and i'm done?

If I can see the stats via the IP address and the pool, Why are people configuring it to show on CGminer.
