I saw the screenshot you attached.
1) To change the shop breadcrumb you need to change the shop page title to whatever you want from the edit page.
2) To change the placeholder text inside the search bar you need to install and use loco translate WordPress plugin. And choose the correct path to translate the string according to your needs.
