I'm not sure what you mean by "lifestyle and other nuances," but here's the Wikipedia entry for your ancestor, a thorough biography with a lot of links you can follow. If you're descended from his only legitimate child, James V, you could be descended from Mary, Queen of Scots, her son James VI (who became James I of England), and through him the Stuart line of English kings and queens. Don't get too excited about this, since James IV had several children outside of marriage, so apparently many more descendants less prominent than the Stuart monarchs, most likely including you.
The article notes that James IV was born at Stirling Castle, which I believe is a day trip from Edinburgh (I've been to Edinburgh but not Stirling). He also built Holyrood Palace, still the seat of the British royal family in Edinburgh. I believe it's usually open to the public (wasn't when I was there because of some royal event). And I assume that the National Museum of Scotland in Edinburgh would have some artifacts and information of interest to you.
Good luck with your travel and research. And if you should discover some yet-unknown claim to the British throne, be discreet about it till you've hired the best lawyer you can find. ;-)
