I agree with Darz. I see
a) Loose Skin -- Mark says that this should shrink back over time.
b) Naturally thin muscles (you're in good company; Mark has thin muscles too -- look at his calves.)
c) Skinny fat
Skinny fat is when your weight seems low but the muscles are flab and the fat is in all the wrong places, like the waist. You see it more on vegetarians and women. If you've even seen the movie "Fathead" (free on Hulu.com), the filmmaker mentions that he went vegetarian for a while, and he "lost weight but it was all in my muscles, I was still fatty in my middle." He was skinny fat. That's why Primal people like to measure weight loss by waist size or % fat instead of raw scale weight.
Here's my 2 cents: If you're exercising one hour a week, then 3000 calories is WAY too much. I would say that you should cut out 60 grams of protein and 80 grams of fat to bring you down to about 2000 calories per day. Really! Once the fat is gone, you can reassess the muscles.
For the workouts, fewer reps at higher weight is what builds muscle bulk. Your legs seem fine For abs, I personally like the Swiss Ball (also called balance ball) exercises; a guy name Adam Ford is an expert, he's on You Tube.
...and one more thing... if you're feeling tendon pain, PLEASE go get tested and go to physical therapy!
I had tendonitis a year ago. I didn't think it was a big deal, and the doc only "recommended" physical therapy. But when I did go to therapy, the therapist said she was glad I was there, because I needed it. It's very easy to aggravate and it takes months to heal. Give your shoulders a break until that pain is gone.
