Hi, sorry my "horrible" english google translate

I bought "multiple seller", "comission" and "shipping".
The question are:
1) I want to show the vendors on the homepage of the same shape as seen in:
http://thecraze.com.
I want to show the products of a seller in the same shape as seen in:
http://thecraze.com/8_lua-lua (for example)
The package I bought is "multiple shop"?.
2) I have read in the characteristics that "multiple shop" is not responsive.
I have the theme "warehouse" to "Themeforest". And "thecraze.com" also has it. I see that it works well.
Or in "thecraze" use another package other than "multiple shop"?
In short, I need to display a list of sellers on page principipal and its products by clicking on them and all that without making modifications to part of what agile and prestashop I can contribute.
Thank you!
Xavier.
