One great way to move from one place to another in New York is using the subway, of course. It's so quick and clear that it hardly needs time to get used to. Having said that, however, you should keep in mind that by using the subway in order to see the many monuments of the city you miss the whole point of wandering and discovering it. So, to avoid that, you need to walk a lot. The walks in New York are apparently so famous for being challenging that people call them the 'death walks', and rightly so.
