Hey Weebee,
You're right, we do have great folks here in our little online community! But then, I've always felt that skaters in general tend to be terrific people. I mean, small-minded selfish evil mean people simply don't strap wheels to their feet and go out to experience the exhilaration of skating, y'know?
Hey, speaking of the joy of flying down a hill on skates - YES, you will want a heel brake if you're going to be skating streets, sidewalks or trails. T-stops, power slides, etc., all rely on friction between the wheels and the pavement to slow you down. This eats up wheels and gets costly in a hurry. Tight turns may work for a while but sooner or later you'll find yourself on a slope too narrow to turn on, or you'll surprise a bike, car or fellow skater by turning into their path, resulting in an ugly collision.
The exception is a closed course race where the only time you should need to stop is after the finish line, and they usually provide you a nice long outrun area for this purpose.
By the way, are you in New York City, or somewhere else in New York State?
There are a number of certified instructors who teach in NYC, and others in Syracuse, Rochester, etc. There's even a Central Park chapter of the National Skate Patrol that offers free braking clinics.
I'm very proud of the three part
braking series I wrote for Inline Planet, but there is no substitute for a lesson from a live instructor. No tutorial can watch what you're doing and give you specific corrections!

Good luck and have fun out there!
