You should always wipe cache, data, system, dalvik cache and do a factory
reset before restoring a nandroid backup or flashing a new or different rom.
Doing a factory reset before restoring a nandroid backup will not make
you loose anything at all because the nandroid backup contains all your
settings, apps, mms, contacts and anything else you had in your rom
prior to making the nandroid backup.
It would also be best if you went to the play store and download the free app
"Goomanager" and use that to make sure you have the latest version of TWRP
for your phone.
