*Gradually decrease your daily calorie intake, what ever is your base level drop a few hundred calories.
*Eat smart and eat clean, eat every 2-3 hrs 40g or so of protein per meal.
*Keep carbs to a miniman and eat them only when necessary, pre and post training and first thing in the morning. You might also try cycling your carbs...I really like this, it works very well.
*Don't snack on crap.
*Bust your butt on the cardio...first thing in the morning is the best.
*Eat plenty of healthy fats, so yes, fish oil is a very good idea.
*Don't waste your money on hydroxy or other junk, if you want just get your own basic ECA stack...far more effective and a whole lot cheaper.
