The Q is available for your bike, but it isn't the biggest bang for your buck. It's lighter, and better looking compared to stock, but don't expect big gains, small if any. Jetting your bike correctly will give you the biggest gain, and it's cheap.
As for suspension, try a couple clicks in (compression) for your forks. For the rear, set the preload to around 100mm and adjust the clickers. Since the rear was bouncing, try a couple clicks out on the rebound (the bottom screw), and fine tune as necessary. Use the compression clicker to balance the rear to the front. Being 135, you shouldn't need heavier springs, the clickers should do. You'll be able to ride faster for longer with a better suspension setup.
Just my two cents,
