First thing once your rooted is to go to the play store and download freegee, https://play.google.com/store/apps/d...l.freegee_free
use that To install a lokified CWM.
Second is to boot into recovery IE CWM if you don't know how to get into recovery there are apps in the play store for that like Goomanager. https://play.google.com/store/apps/d...0up.goomanager
Then Make a backup of your stock rooted Rom. Always have a backup...it has saved my ass on many occasions.
Then your best friend when learning about flashing custom roms is Google YouTube. And XDA...
Here is a good place to start.
Oh and the search function in the XDA app sucks donkey ballzz. So when you are searching the forums I suggest you use your laptop or PC.
