To answer your question OP:
Yes we will get to redo our characters 1 time. Name changes are currently unknown last I checked. (correct me if I am wrong on that)

As for the other responses you got, yeah people don't like repeating things already asked. That, and there are now 3 "Character Creation" videos on the main page. Plus another one that SE made themselves. http://forum.square-enix.com/ffxiv/t...acter-Creation
