Won't comment on Theravada vs. Mahayana; both are valid paths, each suited to different capacities and goals.

It absolutely is worth trying to learn about, since it is not that difficult to find a wealth of material from a more traditional perspective. Even a lot of hippie converts will still write about the religion in an accurate and faithful way (cognitive dissonance probably at work, but hey, I cant say that for certain). There's lots and lots of material translated from Tibetan and Japanese, and a still sizable amount translated from Pali, Sinhalese, and Thai. The material is there - just look for reputable Buddhist institutions and check the lineage or academic credentials of the author.

However, always remember that books have limited value in Buddhism. Find a teacher, and learn to practice. Use books as a supplement.
