Vibrations through gas pedal + looser steering feel?

Mostly in low speed settings, but not all the time. I hear the vibrations mostly through the little lexan wind deflector behind my head. Shifting is a little clunky too - sometimes it doesn't want to go into 2nd, but it's like one out of every 20 shifts into 2nd. Tires are inflated to spec and relatively new.
