Find the latest TWRP for your phone, then the ROM you want to install. Also find the latest GApps for the Android version of the ROM, as well as SuperSU. Once you have these files at a minimum, put them onto a Micro SD card and place it into your phone.
Reboot into CWM and install TWRP. Reboot into recovery once more, make sure TWRP is working, then flash the ROM, then GApps, then SuperSU. Then wipe cache and dalvik and reboot.
HTH! I don't have this phone sorry so these instructions are generic.
