The fastest way to make a muscle grow is to train at with a variety of rep ranges. Each muscle in your body is made up of type 1, type 2a and type 2b muscle fibres. By training with a variety of different rep ranges, you will train every muscle fibre. This will lead to the maximum amount of growth.
After warming up I would do some heavy sets in the 3-5 rep range. I would do your second and third exercise in the 8-12 rep range and finish off your workout with some 20 rep burn out sets.
The high rep sets give you a huge pump and hypertrophy response but are much easier on your joints then heavy weight.
As @stevesmi said, be careful. You can very easily blow out a pec or shoulder by trying to add weight to your bench press too fast.
