1 - That's only if you've contacted them with a different email. Since this is your first time, it is not needed.

3 and 6 - I have no idea what the "201" means but 年 means year,  月 means month,  時 means hour and  分 means minute. So they're asking for the full date and time of when you last played the game.

5 - I have never issued a transfer code in Japanese would somehting along the lines of " 「引き継ぎパスワード」を発行したことがありません. " or "転送コードを発行したことがありません. " I think the second one is better.

In your opening post, the last dot point roughly translates to "Please tell us the date and time you issued the transfer passcode. And in the case haven't issued a code, please tell us the date and time." (they probably mean the last time you played or something).
