Theory on joomla?

Question

Joomla

Guys, we need to build a site on joomla. And there are a lot of questions, tell me.
1. multilingual.
There are two languages ​​on the site. Russian and English.
And there are 50 articles. 3 modules and 2 menus.
In addition to the fact that each module and each article will need to be translated, is it necessary to establish a connection between them? And moreover, the connection will have to be established manually between each text and the module??
Or can it be automated somehow?
3. How to display a list of materials for each category in one place? And depending on the category?
It is necessary for each category to create a module joxi.ru/krDG89gUPalMAp with a list of materials and set the property "binding to menu items" joxi.ru/KAgdkM5czlBBrl ??
joxi.ru/GrqxzelieLjVAz and what would happen like this.
