Where do I start?

I'm 22 years old and have been interested in Buddhism for a long time and consider myself Buddhist. I meditate 2 or 3 times a week and have read a few books on Buddhism. I am more interested in Theravada Buddhism and am not sure where to move forward from here. Should I read and study the Digha Nikaya? I should probably find a sangha near me and go to it, too. For starters, though, should I purchase and read the Digha Nikaya?
