There should be no shortage of recommended reading in the "Introductory Resources" thread in the Discovering Theravada forum.
Have a look through that thread and see what piques your interest.
A modern classic on Theravada and meditation is Mahathera Nyanaponika's "Heart of Buddhist Meditation".
As far as meditation: it might be worthwhile investigating local groups in your area: http://www.buddhanet.net
Personally, I recommend that you also investigate residential meditation retreats if you have the time and means. Many of them are designed to get one established in the foundations of practice and give you an opportunity to develop some depth of practice. My own tradition offers ten-day courses on a purely volitional donation basis.
All the best,
