I don't believe there is any way to zoom out further (yet) than is already allowed.
Some of the lands and areas feel a little empty as content is still being added. I'd expect a fully fleshing out of the world at some point after engine upgrades have been completed. - They are currently adding a weather system in the next week or so.
Chat at the moment is somewhat focused, as most of us that are playing have been playing since early Alpha, so there isn't an abundance of new players to share questions etc. I'd probably recommend looking to join a guild and hope that they can help you. Sometimes chat is better at certain times.
There's a Wiki, but the information is somewhat outdated in parts because the game is updating so quickly that there's not a huge point in updating it at the moment, because the information would need to be updated constantly, and that's a lot of work for any volunteer. I'd expect more concise information once further development has been made.
Hope this helps, and hope I run into you in game
