Here are a few things that I remember that will add to your line of thinking. I believe most of these are from later episodes, so you may have already been planning to mention them.
Repeats:
Room 243
-Patient room where the peace penguin was stolen.
-Later a patient room for a POTW (can't remember which episode right off hand)
Variations of the name Bert in Recession Proof
-Bert (POTW) -Bert and Ernie -Berta's (bar)
Martha Masters:
Odd dialog in regards to her (paraphrasing below)
-"This isn't your office yet." (House to Masters in Family Practice)
-"You're the reason I'm taking it." (House to Masters in regards to the supposed Vicodin)
Reflections/Shadows,etc.
-In Family Practice when Masters comes to Cuddy's office to speak to her, I believe when the camera cuts to Cuddy's profile the shadow being cast on the window beside her is actually that of Masters and not Cuddy.
