Hey David! Welcome to posting at Epoc.
Hopefully that routine you are saying you have will help you out. If it is as good as you are saying, I think if you just stick to it, you'll notice plenty of changes. Even with my fast metabolism I still noticed some changes (even with a pretty weak routine). I think you have a great place to start from and will build from it well. (Im 6'4, and never could get past 150lbs. After my routine started Im usually hovering around 165-168 now - still too twiggy though)
Good luck. Post up that routine as soon as you can. Im interested.. maybe I could borrow it from you.
