Need help on how to to build muscle and lose stomach fat?

i am a 21 year old male, weigh around 150lbs at a height of 5' 8''. i' m at a good weight but i have a fat stomach. i'm trying to replace my fat stomach w/ some abs, but also build my upper body muscle (arms, chest, shoulders) at the same time. i am currently jogging every M-F (doing 4 miles a day), then i go home and work out (M,W,F i work on my chest and shoulders with the bench, and T,TR,S i work on my arms by doing different types of curls). ive been drinking alot of water and absolutely cut any kind of sodas and sweet drinks out of my diet, but i still eat what i usually eat except i eat less than before(i use to eat around 5 meals a day, now i eat 3). i just want to know if i'm on the right track with my workout. should i cont jogging like that everyday or should i speed up my jogging and cut the distance to around 2 miles a day? i've seen improvement on my chest(just started on my arms and shoulders so it hasnt changed),but my stomach is still the same. should i do crunches
