Personally, I would start off by evaluating my current routine, especially food since your goal is fat loss/visible muscle. So maybe take a week and write down everything you eat, including butter/spreads you put on food, oils you cook foods in, drinks with calories, etc. If you don't have one, you can create an account at myfitnesspal.com to help automate the counting. There's a bit of a learning curve for using it accurately, so the first week can be a good time to get the feel of how to track your diet. Also, taking a "starting point" progress photo to look back on.
Once you know this information, you can tweak things to improve your body composition. Perform the SS routine as described. Shave, say, 500 calories off of what you normally consume on a daily basis. Make sure you get enough protein, and fill in the remaining calories with carbs and fat as desired. I'll assume you are 20% body fat, leaving you with 160 pounds of lean mass. Eat around this number in grams of protein to retain muscle mass. Continue this eating and exercise plan for a month, then take another progress picture and re-evaluate.
Again, it's a slow process, and there are lots of ways to structure a diet or exercise plan. The important thing is to make one that's sustainable for you, whatever it may be.
