I didn't read every post, but I saw that you're planning to get a bike. Please don't buy a 600 as a beginner. It is NOT a beginner bike. It's a race bike with lights. A beginner will not do well on a bike with 120 horsepower, extremely touchy brakes, and very aggressive ergos.
Go for something like a Ninja 400, or a Ninja 650 if you're worried about outgrowing it. You wont outgrow that. 70 horsepower. very light. Better yet, get an MT-07. I have one and love it. Same power as the ninja 650, but more torquey and a much better exhaust note. I've been on motorcycles of one kind or another since I was 8. I'm 27 now. Trust me, you do not want a supersport as your first bike.
And one more thing. WEAR GEAR. Spend the money on quality gear. A helmet alone is not enough. Get a good helmet (Shoei, Arai, AVG), get a jacket, gloves, boots, pants. ATGATT. All the gear, all the time. As a noob, your chances of going down aren't low. You like having skin? Wear gear.
Edit: saw your post about insurance. I pay $75 a year through progressive. Liability and comprehensive. It may not be as bad as you think.
