In regards of 1 - I have no clue - I play on PS3 and PC and have not experienced such issue.

In regards of 2 - Once you've logged from a certain location (public IP addres) and / or device at least one it will not lock your password anymore. If you'd still experience the issue the best is to use the one time pasword - it's not only more secure but also completely removes this password lockout "security" fearure. You can either purchase a hardware dongle (it's also part of the Colectors Edition of the game) or use sofware app for Android or iPhone (unlucky though if you're using windows smart phone) - it's called SQEX TOKEN.
