If either of you has time I wouldn't go to a financial planner. I would get a book like Personal Finance for Dummies or spend some quality time reading the

www.fool.com boards.
The short version is always pay the highest interest rate first which is your credit cards. You shouldn't be carrying any revolving consumer debt period. Ever. So get that paid down ASAP. You also need an emergency fund (efund) which you should try to start while paying down the credit card debt. That will allow you to not put something on the card when it comes up (car's timing belt, new furnace, emergency root canal, etc.).
If you wife has a 401k match she should contribute to the maximum match at all costs. That's free money you're throwing away otherwise. If the 401k is not matched and you are eligible for a Roth IRA that's probably the first place to go to.
I'm just doing very simple math here with many assumptions but you're borrowing $40,000 a year for med school. Your wife is making $160,000 a year. Let's assume that you're roughly seeing about 55% of that in post-tax income which comes out to $88,000 per year. You spend $36,000 on mortgage payments which leaves $52,000. If you can cut your monthly expenses to $2000 or less in total that still gives you $28,000 to spend on med school. If you add that to your loan amount you're paying $68,000 in tuition and fees for school? That seems a little high to me.
If you can cut your monthly expenses to $1000 a month, which would be hard unless you're very frugal you could conceivably have $40,000 of your wife's income left per year which would be equivalent to the loan amount that you're taking out.
Now if you're saying that you're investing the $40,000 you're loaning at a post-tax return higher than 6.8% then I say go for it but I get the feeling that you're spending it which means that any money you end up not borrowing will give you a return of 6.8% which isn't bad.
So I'd summarize it as:
1. You shouldn't have $14,000 of credit card debt that you're revolving. You are living far above your means if a $160,000 salary plus $40,000 in student loans annually is still causing you to need to revolve consumer debt.
2. You should try to negotiate lower interest rates with all of your credit card lenders, try to balance transfer to 0% APR or lower APRs as able and then pay down those cards before the 0% expires. You get 11% real return as a result. That's better than the historic stock market returns.
