I've been using the SS program for about 2 months. This is my second time beginning in the novice stage after an injury. I'm 48 and worked through the first month with squats 3x per week. I burned out and needed to rest for almost a week. I had all of the classic symptoms of overreaching described in Practical Programming. I would suggest starting with the Novice program and increasing the weight each time that you train. As progress slows you may want to back off to weekly increases.
Quitting smoking will be challenging enough and my guess is that you'll take in enough calories without using creatine. I have not used it and am still making steady progress.
Good luck to you.
I forgot to mention that I cut the squats back to 2x per week after I burned out.
