I'd get BF done so you know where you are in terms of lean mass. At 5'9" my guess is that your lean mass is going to peak naturally around 185-190lbs (that means at a theoretical 0% BF, which is impossible), so you would weigh in the 200-205lb range at 5-10% BF, which is pretty lean.

I'd refer your diet to the diet forum as well and see where you are with that and make improvements to diet above all.
