It's not all that hard, just make sure you leave at least the minimum spacing around the edges, my father in law didn't and the floor eventually took a spring to it, kind of interesting. He had to go back and re-cut the tight pieces. The foam underlayment will help with any cracks/ seams in your subfloor, just so it's not a large amount. If you get the stuff that glues on the seams, it's more water resistant. My inlaws had 10 (yes 10) kids, and they did their entire house with it probably three years ago. After two years, it still looked new. They just built a new house and installed beautiful pre-finished eucalyptus hardwood plank flooring, after maybe six months it already has visible scrapes and scars. I second the jigsaw route as well, quick and easy.
