Answer 1

Create options (for 1.5.6 this is in the catalog-options menu), then in the settings of each product add the necessary options in the corresponding tab. Write code in the catalog page template that will display options (similar to how they are displayed in the product card - you may need to add them in addition to the template in the controller responsible for the catalog page, I don’t remember exactly).
