which 3 exercises for chest, tri and bi on dc routine?

[skinnyfromtoptobottom]

Hi.
I've just finished my first week of dc training (i started on wednesday though, so i had 2 workouts till now). i'm not sure which 3 exercises i should do for chest, biceps and triceps. i really wanna make those 3 big, they are the most important for me. any suggestions for good full development for those 3? oh, and my tris are already pretty big below my shoulders but they are pretty thin around the elbow. i'd also like to make this even.

i was thinking:
biceps:
- standing heavy barbell curls (pretty sure on this one)
- sitting incline dumbell curls (also pretty sure)
- preacher curls???

triceps:
- dips (i did them this friday and it didn't work too well with those long negatives; should i rather leave them out till my tris get stronger?)
- close grips (if they don't overtrain my chest)
- lying triceps extensions???
- cable pressdowns???

chest:
- flat bench press (pretty sure)
- incline bench press/incline flies???
- straight arm pullovers???

tris and chest are a bit hard. i don't really know what to do. maybe someone can help me out.
