Mike, first off, let me congratulate you because I think you're doing great!
I would try to budget your regular living expenses to your base take-home pay if you can. That way, you would not have to rely on commission just to get by.
I would then use your commission as your war fund to advance your finances; be it debt reduction or investing.
Also, are you renting by yourself? Any way you can either pick up a roommate or at least find somewhere with a shorter commute?
Your phone/blackberry bill seems high as well. Any way you can hack it down?
I think you're off to a good start! I wish my start was as good as yours.
I wouldn't slack off, but I would certainly breathe normal and give yourself a pat on the back. You're doing just fine.
