Styles are stored in templates and in documents. Changing the style in a template doesn't affect documents created with that template unless you actively tell the document to update or have linked the document to the template up front.

So, the answer to your first question is no and to the second is yes.

>2. If I create a document and assign certain parts of the document to various styles (Heading 1, Heading 2, etc), and later change something in a style, will my document be automatically updated with changes?

That depends on where you change the style definition. If you do it in the document, yes, it will affect the entire document.
