Since you have so many questions, this forum is 
better suited for you, since it focuses primarily 
on Yahoo! Japan.  They will probably also answer 
questions you haven't thought of yet.

Here is also an FAQ/information page that should 
assist you as well:

And please understand that I'm not trying to give 
you the run-around; visit these links and they 
WILL HELP YOU.  Regulars on this board try to 
steer newbies to these links so the Animanga 
forum doesn't get too cluttered with YJ questions.

Your Dorothy auction link appears incomplete, so 
I can't help you there.
