trapping and first touch is all dependant on being comfortable with the ball. it takes time to develop this feeling. i'd suggest that you stick to basics and try not to folllow int eh footsteps of milan baros so much. if you watch any liverpool this season you'll know what crap first touch he has. frankly i think you haven't picked the best striker to model yourself after
but since you ask we'll all help you.
if u've noticed, balls bounce off baros like he is a wall. i'm guessing u do the same.
if u're going to control a low, ground, fast ground pass, you know a few things. first the ball will have a lot of pace. second see the path of the ball. then you'll need to know how to control it. now if u want it to stop at ur feet without flying away, using the side of ur foot would be ideal.
how to achieve this. well u know how to pass with the side of ur foot? what i do is the same thing, lift ur foot and have the side flat and lifted off the ground a bit. that way when the ball reaches u, u've got a space between ur cleats and the turf. what that does is the top of ur foot (arch area-side) stops the ball at a high point in teh ball, and bleeds the pace on the ball and absorbs the momentum. u'll find that ur arch is almost a perfect fit. if u had ur foot just there, it'd hit the foot, no pace would be absorbed and the ball would rebound. simple physics. this takes a lot of practice. be patient. you've still got a lot of time, u're a young lad. play with the trapping, practice against a wall. it's helpful. take a ball, get a brick wall with grass surrounding it. keep side footing ur pass into the wall with a lot of power, and then trap. it's terribly simple.
good luck, hope this helps
