You just want to find out who the influential "key players" i.e. the people who carry weight during residency selections are and impress them by working hard and being likeable. These people typically include, the chairman, the program director, the tenured attendings, the residents and the junior facualty only if they are the "rising stars" (next PD, "the spine guy", the next leaders in ortho) - in that order. I know that sounds very obvious but you would be surprised..... If you can impress the chairmen, PD, and residents you are doing very well. Chairmen can be hard to access so adjust accordingly. Whatever services these people are on are the ones you should do - peds, hand, spine, whatever. You get to know the residents on your service and the others by doing lots of call (trauma) and presenting at fracture conference. Don't do trauma because its trauma. The PD or chairman may hate the trauma guy - but that's program politics that you probably won't have access to. I compare this process to rushing a fraternity as much as applying for a job.
