Answer 1

It depends on when you want this action to happen. Like always with prestashop, you have 2 possibilities :

Override an existing controller

For example if you want to add a product to the cart everytime its created, you might want to override CartController. In that case here is the answers to your questions :

1. In the override/controllers folder.
2. The parent controller you chose, for example CartControllerCore
3. The same as the parent controller. Check the official doc about the dispatcher, it's pretty usefull

Create you own module

I think this is the best choice if you want to have a real control over when you trigger this action.

1. In the modules/you_module/controllers folder. The official doc is also a great place to start.
2. ModuleFrontController
3. Refer to the page about the dispatcher I gave you above, but the best way to trigger your action is to use the hook system.
