Looks like you're on the right track so far!
A couple of things I wish people had told me when I was that age:
Don't try to catch the rocket. You'll probably get the motor, which has just been on fire.
Estes chutes usually have a circle in the middle. Cut that out so you have a hole in the middle of the chute if you're going to be flying higher. It will bring the rocket down a lot faster so it's less likely to meet a rocket eating tree. Fins can be glued back on, but trees and lost are forever.
Concrete is unkind to rockets, so launching on a field is better than a parking lot. Of course, a parking lot is better than no launch at all!
Once you see composite motors (usually E and higher), you'll be hooked for life.
Keep an eye on the delays. If the motor says B4-4, make sure you use that and not a B4-7. Too long a delay can lead to lawn darts.
Welcome to the hobby!
You can find clubs here:
https://www.nar.org/find-a-local-club/nar-club-locator/. It looks like there's a club on Long Island, but I don't know how active they are. I've heard of a major launch in NY that might be worth a drive sometime (Upstate, Potter?). I'm way out west, so I don't know for sure.
