How do you manage changing state overtime? Do you re-render the whole template?

Can templates be nested?

You use standard DOM operations to update state, like innerText and classList.add, defined inside the JS class that orchestrates the component.

Nesting works using the same concept. A parent template either picks one of its child nodes using this.fragment.querySelector or using document.createElement to mount a child template to. You then use this.addChild to opt into garbage collection.
