Alright..so I checked out your pic thread on the other board and I will say one thing: you are not skinny fat. You are more like an endo who (much like myself a few years ago) probably sat around and just ate whenever and whatever you wanted.
You don't need to be getting in depth into diet to start losing that. Make sure you take in a adequate amount of calories and aim for 2lbs/week of loss. Bulking right now would do you absolutely no good as it will just add bodyfat (and probably be counter productive to a good mindset!)
Try and lean down at least 20-30lbs, then maybe go for a clean bulk and add 10lbs back, and repeat..this will keep you from plateauing - which is more or less an inevitable thing when trying to diet down a lot.
Make sure you are lifting heavy to retain as much muscle mass as you can and do moderate to light cardio (walking, incline walking, light jogging.) The fat will start to melt off but it will take time as you do have a bit to lose, but you'll get there. Over analyzing can be good, as it will help you learn..but understand you might not notice a physical difference for weeks even though things are changing. Don't even step on the scale for the next year, just follow a clean diet and good lifting program !
