I'd like to add my own tips for 'newbie' riders...
Eye protection. You'll get a bug hit at some point in time and more than likely it won't be when you are trudging up a hill at 10 mph but on a descent at 35 mph. Had one in the forehead, above my glasses and below the helmet, yesterday and it hurt. Can't imagine what may have happened if it was in the eye.
Also, it doesn't matter how many blinky lights or orange/neon clothes you wear. Once you get on a bike and are on the road it seems that a Star Trek cloaking device gets on with you. You will not be seen by some folks in vehicles. Make eye contact
