Ok you dont need to do 2 different Incline presses your are doing the same thing when you do DB and Barbell so your technically doing 6 sets of incline bench dont forget 2 warm up sets so really doing 8 sets or incline bench.. Try this, this is my chest workout yeah not evenone is the same but it has worked great for me.

Flat bench BD presses (2 warm up sets) Then 3 sets of 10
Incline Bench either DB or BarBell (NO SMITH MACHINE ill tell you why later) 3sets of 10
Weighted bench dips 3 sets of 10
Cable crosses overs with a 2 second hold while crossing 3 sets of 10

OK now why did I say no smith machine well number the smith machine Does not use core stabilizers and restricts movement that could result in injury.. Think about it, when doing a bench press or a should press do you press the weight stright up and down in a perfect stright line? No you actually cruve you may not know it but thats why your body does naturally.. So the smith machince forces you go stright up and down which is very bad for joints. Well thats all I have know im sure I can come up with more things later on.
