This is the only LSAT book I have right now, but I like it. It has uses only real LSAT questions from previous exams and contains 3 real LSAT practice tests. The online stuff is mainly a tracker, a diagnostic test, some video tutorials, and some extra quizes.
It has study section on each of the different areas of the exam, then a list of practice questions. Each question is explained in detail. Then there are the three full size practice tests with explanations of the answers (these are older tests) and some extra hints and tips.
