Really the same things you did 3rd year to be successful on the wards....
Here are some things that come to mind:
-Be on time/early
-Know everything about your patients
-Read up on your pt's conditions daily
-Come up with a good differential, assessment and plan for your pts
-Try to anticipate your team's needs and the next management steps
-Bring some extra order sheets with you to rounds
-When you do an admit take a shot at writing your own admit orders
-If a unique case comes along or something specific is talked about arounds feel free to find a relevant article and print out copies for the team
-Be willing to take admits, answer questions, and do presentations but don't be "that" person and go overboard by jumping in on questions meant for others or trying to show other students up by rattling off an obscure fact you just read the night before.
-Your interns and residents are busy, so offer to help with some scut/paperwork if allowed.
-This goes along with knowing your patients, but check up on them multiple times through the day as your intern/resident may not be able to and you will.
-Be sure you follow up on any labs/imaging and let your intern/res know if there's something that needs handling instead of waiting until the end of the day. If there was an error, missing labs, or a scan couldn't be done then you may be the first to find out and can come across as an asset to the team if you bring the issue to their attention and get it handled in a timely manner.
So no real secrets IMHO. Just be willing to work, learn and read daily. It basically comes down to will they enjoy working with you and can they trust you. You're interested in medicine so hopefully the genuine interest will come through.
As far as pocket books, the main ones I've seen around are pocket medicine and washington manual.
