I just moved to NY myself a few weeks ago, and am generally a pretty light sleeper. I didn't have trouble falling asleep, but I had trouble with waking up at 4AM, as soon as sunlight really started coming in. Luckily, the solution was easy - $100 or so gets a set of blackout curtains that can just about make the place pitch black in direct sunlight. Apparently New Yorkers are oddly averse to curtains for some reason... Noise is a little tougher. Luckily, my place is pretty well insulated. But white noise like fans and such and earplugs can help a lot.
