Speed: When you are riding down a nice straightaway and you feel like goosing it, try to start in a low gear. Work that gear to its full potential, and then shift up (if you have an automatic bike, don't worry about this). Once you get up to your speed, slant your back at a 45 degree angle, bend your arms at a 90 degree angle and stand up. When standing up your legs and arms act as additional suspension when going over bumps. This keeps you in better control and will conserve energy.
Turning: The trick to getting maximum speed and the best setup in a turn is control. When coming into a turn, pick a good line that isn't going to run you off the track. Stick with it and keep steady power. Keep your outside elbow up and your inside leg out. Have your leg sticking straight out in front of you by the fender. This will help you keep your balance, and you can dab your foot on the ground if you slide out. Once in the turn, look where you want to go. Also keep your butt on the outside of the seat and apply a little pressure to the outside foot peg, this helps put more weight on the outside of your bike, giving you more traction. Remember to finish your braking and shifting before you enter the corner so you can concentrate all of your attention on getting through it. Sometimes using the clutch while exiting a corner will give you a short burst of power.
Jumps: Hitting big jumps can be scary if you are not comfortable with your riding ability yet. Try little table tops at first; they are very easy and provide a steady landing almost everywhere. Lift up your handlebars and stand up a little. Once you get skilled with that, try a double. Take off the bottom of the face sitting down. By the time your front wheel is off the dirt you should be standing up. Once in the air, position yourself comfortably but sturdily for a landing. If your front end is straight up and down, don't panic! Hit the back brake and it should lower gradually. Before you hit the ground, give a little gas so your bike will flow smoothly.
