Same sort of situation...graduating very soon and considering what type of atmosphere I need for my first job.
As for continuing to study - YES! When they kept talking about being a "lifelong learner" in NP school, they were NOT kidding! One thing I learned from my final preceptor was to have reference books you are familiar with close at hand. She had a little musculoskeletal book from the 80s that I'm trying to find online - concise down-and-dirty info you need to lay your hands on quickly.
Subscribe to one or two journals in your area of specialty. Too many journals just pile up on your shelves/desk/floor and are ignored. Continue to look up information on any diagnosis that is new to you, or any meds a patient comes in taking that you're not familiar with...just like in nursing school
and NP school.
UpToDate, Medscape, and epocrates have become my best and closest friends and I look things up all the time. Keep your eyes open for continuing ed opportunities where you can get your required hours, but that also offer information updates in areas you feel weak. For me, that's going to include ortho exams/treatments.
I also agree with the previous poster that those of us who are smart enough to know what we don't know are safer providing care to patients than are those who think they know it all.
