I commend you for wanting to what I hope is a change in lifestyle. This is a serious commitment that takes dedication and patience.
I think looking good should be ancillary to your main gain which should be to live a better life through consistency in a proper diet and regular resistance training. To that end, I will tell you that you will not get to your goal with any supplementation unless your diet is modified. From your post, it looks like that is your main issue. Before you can begin to build serious muscle, you must fix what you have to be able to move on. It is a very difficult task to lose body fat and gain muscle and what you end up with is half assing both and not accomplishing what you are looking for. Break up your goals- modify your diet, add cardio to your regimen, and lose body fat. I would seriously recommend getting your body fat taken either with calipers by an experienced trainer or in a water tank(if that is available to you). Once you have some bodyfat(the mirror will be your friend) begin to add resistance training. How you split your body(workout wise) will be determined by how many days you can be in the gym. You will need to make sacrifices - remember what your end result is to be. This is a long term investment in time.
I apologize if I am coming across as hard or shrewd, but I have seen to many clients in the past want the easy way out and then be disappointed when they don't get the results they are looking for. Consistency is always the key , especially when it comes to you diet. How about some more information on yourself? What does you current diet looks like? Do you currently incorporate cardio in your daily life? Are there any pre-existing conditions that may be an obstacle in beginning this journey? Lots of questions I know, but need more info so the members here can provide some direction on where you to go.
