Those are all back exercises. Your back is not the problem. Your core is. When most people say "core" they mean the front side of you, not the back side. Crunches, Leg raises, anything that works your ABS. Those are the exercises you want to emphasize for the next several months. If you did nothing else but work up to 200 situps (or crunches) you would see a marked improvement in your back pain.
