Unfortunately, shoulder surgeries are one of the worst to recover from. Take it really easy and follow your surgeon's recommendations religiously for the first three to four months (when he will most likely have you do very little, and you will be very frustrated). But if you screw up in the those first few months, then you really risk not healing correctly. After the first month of strenghtening exercises, you can push yourself a bit more. Wishing you the best on the surgery and a successful recovery, and hope to see you at the '13 Mexican 1000!
