No, root is root. Once you have rooted, you uninstall the Towelroot app. Being rooted won't make a single bit of difference to battery usage. That is in 99.99% of all cases down to an app that a user has installed, or sometimes a change to a system file or setting that a user has made after s/he rooted their device.
Wiping data as you say removes your stored data (contacts etc), installed apps (from the Play Store etc) and sets up the phone as it was when you turned it on for the first time.
It might be worth backing up any pictures or music you have on the internal sdcard, but the external sdcard won't be touched.
