Cookies is one way tracking is done, and by far the most prevalent.

That will kill basic cookie-based tracking, yes.

Yes. But you're hurting yourself more than you need to if you delete all cookies. There are different kinds of cookies. First-party cookies (i.e. cookies issued by the site you have a session with --the site serving up the main page that you're looking at) help you stay logged in, and are very convenient and only "track" you on the site that you're on. So killing session cookies only makes your life less convenient while not stopping tracking. So its the third party cookies you want to delete.
