My advice to you would be as follows:
1) Think about what you need the MBA for.
2) If you want to work in an MBA type role (read strategy consulting, etc.), then the question would be - why are you in law school now? That aside, I would recommend that you finish school as early as possible, try to get some decent work experience and throw your hat in the ring for admissions to top B-schools. Your undergraduate GPA will be a factor, but the rest of your profile should have enough to mitigate that.
3) But if you are happy being a lawyer, and just want some interesting work experience that has elements of business strategy in it, I would recommend that you add on the extra year right now, and get into a good (meaning something that you are likely to enjoy) role immediately after your dual degree.
Best wishes,

First off,
the bad: I have a 2.4 grade point from undergrad in an easy major at a directional state school. (Think like political science at Southern Illinois) I actually had a downward trend.
The good: I'm currently a rising third year enrolled in a top 30 law school (Minnesota/USC/Emory/Notre Dame/Wisconsin/Indiana) with above a 3.75. On the curve I'm in the top 10-25% of the class. I currently have no work experience but I'll probably have an offer at a biglaw firm and I have a decent shot at MBA type F500 corporate strategy/consulting offers. I have above average extracurriculars from both undergrad and grad school. I also have a 730+ GMAT. I'm also a white male.
The big question. I currently can do a JD/MBA with a top 30 MBA program that will only take an extra year of school right now. Or I can wait and try and apply to business schools in 3-4 years after my degree with pretty good work experience. I'm curious whether with a good application, I'll have the ability to go to a top school?
Other factors: Financially I don't think that a school that doesn't have incredibly good on campus recruiting and name recognition will be worth it in 3-4 years versus going immediately right now. For example I think going to Northwestern in 3-4 years might be worth it since I'll have access to more employers and my average classmates will have more interesting experiences than going to say UNC in 3-4 years. Nothing against the UNC level schools but I'm not sure if financially it will be worth it if I can go to a somewhat comparable school right now for much cheaper.
