Conversations In Care is an informative web-book about physician/patient communications, mostly for the use of doctors. There's a great chapter about breaking bad news to patients, non-verbal communication skills, and even one about how the physician feels when he has suddenly become a patient in his own hospital (as you are aware, House-fandom is sadly lacking in doctor-turned-patient fics. Ahem.)
Can be used for all characters, but the oncology-oriented nature of the site makes it particularly relevant for Wilson-centric fics... it can really help the medically untrained author understand some of the rougher, emotional aspects of Wilson's job, and perhaps why he's so good at it.
