http://makezine.com/ and the http://makerfaire.com/ have done a great job with a community that encourages kids with a variety of interests.

http://www.meetup.com/ is great for finding people in your area who want to geek out together over something in common.

I don't have great book recommendations other than https://www.amazon.com/Manga-Guide-Databases-Mana-Takahashi/... Read the customer reviews. I'm a greybeard and I enjoyed it and lend it out to my friends. The publishers https://www.nostarch.com/ have lots of similar books.
