Beginner's questions for Verizon S4 5.0.1

I just got an S4 and have very little knowledge on what it takes to root it and install a clean version of android lollipop. When I got the phone I updated to the latest OS version (OTA, 5.0.1). From what I understand, the only thing I can do is use the Kingroot PC program to root, but its all in chinese so I dont know quiet what to do (is there a guide out there?). After that, I would like to install a clean, stock version of android, but I'm not quiet sure what is involved with that process (ROMS? Which one can I use? etc.). Any help is greatly appreciated!
