Stick to basics? 4 sets of 8 of flat bench is NOT enough for your chest workout. You're not going to see much of anything gain-wise from doing this.
For your chest you should be doing
1 or 2 warmup sets
4 sets of 6-8 reps each for flat and incline dumbbell bench. You should be using a weight where you fail around the last rep.
After that I would try some incline and flat barbell bench for a few sets each.
4 sets of weighted dips to close.
