Health system and pursuing multiple degrees

According to http://www.publichealthnewswire.org/?p=3262 and http://www.ama-assn.org/amednews/2012/04/23/prl20423.htm:
More medical students are pursuing degrees in other areas amidst our changing healthcare landscape; in the case of these students, an MD just doesn't quite cut it anymore.  This includes MBA, PhD/DrPH, JD, and MPH.

Although I'm currently a Public Health student (MPH), this got me thinking about my own self since I'll most likely be working closely with nurses/physicians at some point in my career.  (Come to think of it, a few months ago I spoke with a parish nurse about health programs at a local church - these nurses are also sometimes called faith community nurses, church nurses, or health ministry nurses.)  But also in the way I can be more well-rounded once I step into the job world again.  I know some of my classmates are thinking of pursuing more schooling as a physician's assistant, doctor, nurse, or lawyer after this.

What are your thoughts on being a more well-rounded job candidate?  What skills are REALLY needed in this "changing healthcare landscape" (e.g., accounting, marketing, budgeting, business...)?
