Exercises for max results

I am new to the whole body building thing but i have read a great post on this site about bulking for teens and now use a routine of:
 
Day one: Chest, Tris
Day two: Bis, Back
Day three: Shoulders, Legs
 
I am happy with this pattern but not really sure which exercises to be doing for which days.  I have been pointed in the direction of a few exercise sites from here but they always have a huge list and im not sure which to choose even though i know some are more effective than others.  These are the ones i am doing at the moment:
 
Day one: Flat bench, Chest press, Dumbell Flys, Tricep pulldowns.
Day two: Cable curls, Barbell curls, Lat pulldowns, Deadlift, Bent over rows.
Day three: Leg press, Dumbell shrugs, Shoulder press, (the other two leg machines which i cant remember the names of, one where you flex your kness down and one up)
 
I know this routine is far from great and that is why i need a bit of help with it.
I would love any information of no. of sets and erps to perform aswell.
I dont expect anyone to go massively out of their way and develop a full program for me or anything but any help you could give me would be ace. Ta.

hey tarros awesome of you to join us in the forum ..
 
the routine your on seems fine .. i would suggest you stick to compound lifts such as deadlifts, squats, bench press since you are looking to bulk ..
 
also, do the compound lifts first before you work on your smaller muscles .. like your day 2 .. start with your back first workin deads then bent rows .. then work on your arms ..
 
since your a beginner .. you will see pretty good gains fairly quickly .. so i guess a simple 10 rep 3 sets would be fine for now until you get your form down ... then change it up 8-12 weeks or when you feel your ready .. dont forget your diet ..
