I had good results from greeting the students as they came into class, calling them by name, and, most of all moving around throughout the classroom (proximity). I especially liked--and found useful--Literature on Active Learning, the book Freedom to Learn by Carl Rogers, and any of the books by Harry K. Wong. Many of these are available from your library.
That is a great answer above. I have also found it extremely useful to teach - and most importantly, rehearse - the way that I want my students to act in my classroom. I teach them basic procedures such as how to ask and answer questions (such as: "While another student is asking a question and it is being answered, wait to raise your hand until the answer is complete. That way you won't miss an important answer.") If you don't set the expectations in your classroom, your students will do it for you. There are many great books on the concepts behind classroom management that will help - I believe my favorite is called (approximately) "Taking Effective Control of Your Life" by William Glasser, M.D.
