You have nothing to be embarrassed about. There are plenty of people here in your position, and much worse. Hell, 4 years ago I was 255lbs and mid-30's bodyfat. This is a support forum, and you'll get nothing but support here. Anybody wanting to hurt member's feelings will be swiftly banned.
I'd start your protein at 250g based on 205lbs @ 25% bodyfat. For overall calories, I wouldn't go over 2000 for a while to be honest. In fact, I think you'd do well in the 1700-2000 range, 2000 being a single high calorie day. I know it sounds low, but I've cut on fewer calories than that... without any muscle loss.
Foods pre and post workout are, in your case, necessary. To keep things simple, i'd start you with 6 -8 meals/day (depends on the length of your day, basically eating every 3 hours or so), with carbs in only your pre and PWO meals. Possibly in your first meal of the day as well. I'd stick with all complex carbs - the idea is to keep sugar intake as LOW as possible, keeping insulin spikes at bay and BGL stable.
I don't have the time to step you through an entire diet, some of the other guys will help you along, but in the meantime I suggest you read my cutting 101 sticky here to get started:
