Do you need to include all that detail in your text? My guess is that with that first sentence, if there is a need to include the exact day, you don't also need to include the year. So if I were writing it I would say either 'the 22 December meeting', or 'the December 2014 meeting'. Clearly if I am giving this information as late as November 2014, I would have used the former. But if I had been giving it back in 2012, I would simply have said 'the December 2014 meeting'.
Similarly, my guess is that you could probably get away with saying 'the Indiana man'. In my experience many people will say they are going to 'London, England'. Now there really isn't any need to include the country because everyone knows where London is. There may be times when you will want to distinguish London, England from London, Ohio; but they are I would think, few and far between.
So my suggestion, before worrying about the punctuation is to ask yourself if you really need to include as much detail; which in my view tends to get in the way of good comprehension rather than expanding it.
