Hard to give you a timeline without knowing the severity of the injury. If it is disc related, it could take some time to heal.
Usually you will be able to perform some exercises much sooner than others. Exercises like bent-over rows, squats, deadlifts and even shrugs, calf raises w/ the weight on your shoulders, ab crunches and shoulder press all create high spinal loading and could increase your pain. Since your spine was in a flexed position at the time of injury, exercises that put you in flexion would probably irritate your injury. However, without examining you I don't know what movements either increase or decrease your pain.
Did the doc give you any kind of stretches or movements to work on? Also, right now it is more important that the doc has a good grasp on your injury and knows how to treat you and get you started on a rehab program than it is on how much he knows about all your training. However, as you heal and progress from some basic exercises, it will be important for him to know what your athletic goals are. If he doesn't know the exercises either bring pictures or demonstrate the movements so he can see what kind of spinal movement patterns need to be trained in order for you to avoid re-injury.
Also, the book is not out of print, you can get it from the author's web-site, backfitpro.com and I know it is available through a company called OPTP.
It runs about 40 bucks but is worth every penny.
