In short, what area of the universe was Star Trek exploring?
Our galaxy, the milky way.
Was the entire series limited to our galaxy, or did the crew ever visit other galaxies?
I believe crossing the distance between galaxies is a big deal in the Trek universe - the Federation tech isn't there yet. I can think of two (also shown on the map below) where they had help:
Can anyone explain the Star Trek geography (i.e. quadrants)?
Our galaxy is labeled by cutting it like a pie into 4 pieces: Alpha (Federation location), Beta (Klingon/Romulan location), Gamma (ST:DS9 wormhole), Delta (ST:VOY setting).
Does anyone know how the travels of the Enterprise relate to our universe in physical space?
I like the map from here:

- The limits of explorer local space
- ST:VOY Voyager's route
- The ends of the ST:DS9 Bajoran wormhole
- The Great Barrier from ST:TFF
- The points where Enterprise and Enterprise-D left the galaxy
