Okay. Questions:
Did you make two different Square Enix accounts or two different FFXIV service account? Playstation Network accounts can only be bound to one Square Enix account. Also what beta phase was this? are you legacy?

From what I understood is not possible to make the PS3 keyboard/mouse identical to the PC version because of UI memory limitation. The only style of gameplay on is controller. You can use keyboard to talk and open shortcuts (alt/ctrl + whatever).
