The fork steerer tube on that bike doesn't appear to stick above the head tube to allow you to attach the bars you want.
Even if you could, the larger width tires have more rolling resistance than the standard hybrid bike tire. The narrower tires would be more beneficial to you if your riding 30+ miles.
At only 3 months old, your better off getting as much money as you can out of the bike and put it for sale on craigslist or see if the bike shop will give you a decent amount of $$$ on trade in against a true hybrid bike.
The longer you wait, the less your bike is worth.
