Excluding X-Men and Spiderman everything Marvel is in the same universe with the film stuff, (obviously the comics don't have this divide because Marvel own everything).
The Thor films sort of bridge out into 'Marvel Cosmic' territory a bit but GotG is probably Marvel's riskiest film because it's pure space antics - Peter Quill/Starlord is the only character from Earth and even then he's only half-human. They're not in the film but Marvel Cosmic is Galactus/Silver Surfer stuff, threats to galaxies/the universe, god-like cosmic entities etc - it makes the Avengers seem like small fry.
This. They're definitely try to raise the cosmic stakes, presumably for Phase Three and the third Avengers film where Galactus is the big bad...
