Some more advice: the school's reputation is not important at all, especially for a postdoc situation. The most important factors are your productivity (of course) but also the reputation of your PI. Once you leave the postdoc, if you can say you worked for so-and-so, whom people may know, it is much better than I worked at so-and-so university. For security, you should also consider the funding record of each PI (you can check this out for yourself on the NIH website to ensure you are not being misled). Also consider the type of grant will be covering your work (R01, etc)? When does this grant money expire? How long will you be expected to remain there? What is the publication record for each PI? How many people do they have in the lab? How many postdocs vs students? How often do people publish when they are there?
Also, since you have a family on the way, I hope you are also considering health insurance coverage. Many postdoc positions do not come with funded health insurance, and instead these fees will need to come out of pocket, further lowing your income. A position at a medical school or NIH, however, will typically have health insurance provided.
Find a PI with an extensive publication record, who is well known in his/her field, who has funding for the next 4-5 years and who is not just running a data factory. Whichever situation (Nashville or Philly) best meets these demands, take that one. If neither, keep looking.
Finally, in regards to your other questions, go ahead and ask the PI to meet the NIH off-campus minimum, but again the likelihood that he will raise the amount in question is low, especially when there are a plethora of postdocs out there, some of whom will work for the low pay.
Science is simply common sense at its best that is rigidly accurate in observation and merciless to fallacy in logic.
