good training school is a must. your bike is too big for a beginner but no matter you can still learn on it. Check out this site, it has a lot of useful info
http://www.msgroup.org/DISCUSS.asp You should watch what the motorcycle cops do, most of them have good habits and you could learn from them. Also, stop one of them and chat about learning to ride, they'll be happy to point out schools in your area.
When you stop left foot down, right foot on the rear brake, always in first gear. Check to make sure your bike is not too tall for you.
Now to the important subject of trusting the advice of strangers on such important issues. Unless you know the person is an expert in his field don't listen to their input, it's your life on the line. For example what happens if you need to do an emergency stop? What happens then to the "stop gradually" technique? Also, keep dragging your feet and one day you'll hit a pothole and brake one of your legs as it hits the pavement or gets stuck in the hole...
School, is the best way to go... Good luck out there.
