Personally, the only graduate degree that __I__ would go for would be an MBA. That being said, I'm taking Mechanical Engineering so I graduate with a professional degree and I see no merit in going any further educationally unless I either a) wish to teach or b) want to have an easier time getting into management (with an MBA).

However, more school on paper usually looks better and if you feel like it will advance you, go for it... but you probably know that already. Do you see yourself using it to get a better job or to open up Ph.D/instruction opportunities? Maybe think about that before you jump into it if you haven't already.

With regards to the find a job/don't find a job dilemma... again __I__ personally would probably want the security of having a job but being the employer who would be hiring and investing the resources into hiring you/training you only to find that a week or two into the job (if that!) you're leaving would leave me less than impressed.

Don't burn your bridges!
