what items to transfer?

i just finished origins and plan to start awakening, and i was wondering what items should i transfer to awakening? armors and weapons and any other useful items, please help, thanks

oh also, do i need to finish the game before i transfer? does seeing the ending make a difference in the transfer? i ask because after getting the ending i cant unequip my party memebers anymore so i cant get their items and weapons, so i would have to unequip them before the final battle, but that would make the final battle really difficult, so what should i do? thanks again
