first step in Ryu

Dear Takashi Irie,
we just get your Ryu theme and really love it.
We would like to have some information about the customization of Ryu:

Why the icon “standard” doesn’t work? I don’t understand what it is for.

I would like to remove all the icons on the right (standard, aside,image,video,quote,link).
Is it possible?

Is it possible to add all the titles at the top of the posts (and not just for the standard one) ?

is it possible to remove all the buttons of the widget area?

Is it possible to add the widget area in the same field of the primary menu?

Is it possible to add the categories in the same area of the tag?

Is it possible to put that information (date,tag,category) in the same line?

What is the link post ?I don’t understand what is for.

Why the link post title isn’t visible?

Is it possible to add the related posts at the end of the post?

Is it possible to have a shape as a background of the posts? ( see Inspiration Laboratory theme http://theme.wordpress.com/credits/inspirationlaboratorydemo.wordpress.com/ )

Thank you in advance for your help
and greetings from Florence!
