Hi,

If you want to increase the products per row you will need to modify the current distribution of the columns.

The whole website is based on 960 grid layout, which gives maximum 8 products per row without column and 6 with a side column (look at the second 16 columns grid).

You will need to go to every template that lists products and change the following:

to (without side column):

or to (with side column):

About the price;

You could add a Categories module from Extensions -> Modules to the Home layout. If you want only one level to be shown in the module, you will need to modify

The number of products per page is set from System -> Settings -> Option

Generally, the website you have pointed is totally different from Shoppica and you will need a lot of modifications to get the wanted style.
