I am new to prestashop and am trying to customize the default theme of version 1.4.7.3. I want to have the below layout for my home, category and product pages.

1. Home Page: Both the left and right columns will be disabled. The center column will occupy all the space between Header and Footer section.
2. Category Page: Right column will be disabled. Left column will be as it is. Center column will occupy the space for center and right columns.
3. Product Page: Left column will be disabled. Right column will be as it is. Center column will occupy the space for center and left columns.

Please let me know what all changes are required to achieve this layout.
