Don't fear the big dog:
You might think the driver is more than you can handle right now: It's the longest club in your bag, and the head is gigantic. The truth is, built into that big clubhead is more forgiveness for mis-hits than you get with any other club. Have a few driver keys to rely on.
First, tee the ball nice and high. Second, take the club back smoothly and make a full body turn, getting your back to face the target. Third, swing through the ball; just let it get in the way of the clubhead through impact. Last, hold your finish. If you can finish in balance, you've swung at a speed you can control.
