rnr has a great suggestion. The Colorado DOW video is excellent. They show you A to Z how to bone it out and what they use for knives, tarps, leaving evidence of sex on the carcass, etc. An excellent DVD and well worth it. I can't speak to the aging process of bone in vs. bone out. I do know that the meat will also age in the freezer as well. There was an article on it in the American Hunter a few years back on the subject.
Here's the link to the DVD:
