Been quite a few times, the place is absolutely buzzing 24/7 you'll love it!
Booked online for later trips, absolutely no probs, stay with names you've heard of.
Any of the big Airlines, BA, Virgin, AA, etc, all are good, so go for best price. many do deals with hotels, again, stick with names you know.
Stayed here a few times, perfect location.

Statue of Liberty, Ground Zero etc, for this trip, I would locate myself around "Times Square" 5th Ave, 42nd Street, There's a Holiday Inn in this area, its location is ideal.
Don't eat in the Hotel! NY is way too good to eat in a Hotel! any time of day
Wouldn't bother with the Zoo, you can do that in England, and theirs simply more exploring to do
If you want a more culteral experience of NY, then you need to be at the SoHo end of town, not far from Ground Zero/Financial District. Bars, Cafe's, Restaurants, Art galleries, Bleecker Street is the area to head for!
Bus tours are a great way to see the sites where you can drop off anywhere, and pick up another tour bus later, same as how it works in London. Do the night tour, which takes you over the Brooklyn Bridge, and you get a stunning view looking back to Manhattan
Don't hire a car, you'll never park it, or fill it up with fuel for that matter... no gas stations in NY.
Taxi Drivers will rip you off if they can! always be confident that you know where you're going, and make out like you live there!
NY is very very safe at night,
Don't do the Statue of Liberty via the Staten Island ferry like everyone says! the closest you'll get is a 1/4 of a mile away, pay up and do the proper tour!
