Eat healthy and get plenty of protein. That is all the supplements that you need at first.
If you want to lose fat, but still gain muscle then start by lifting regularly and doing a small amount of low intensity cardio after working out. Better yet, do cardio in the morning and lift in the evening.
Odds are that if you are not eating healthy now you will lose the fat just by eating healthy and lifting.
