When I'm satisfied with the general volume a shell modifier helps me to give thickness to the piece. In this phase, I don't usually bother that much about every single rivet, hole or cut, I just try to develop a good quad topology of the main volumes. Of course the topology is done by taking count of the main cuts and holes, but the rest can be done easily with a normal or bump map. It's up to you to decide how much a single detail is worth to be modeled or can it be put into a bump map. I usually adopt a "comfortable" criteria...it means that if something looks tricky to me to be carved or extruded into an existing geometry I usually put it into a normal map. When you make something for production, you don't usually have much time to model everything, so you need to set priorities.
