About the quick serve in tennis, I have found that it is a matter of a flick of the wrist. Try holding the wii remote vertically, push A for the tossup and when the ball is at its highest point flick your wrist quickly forwards and almost always you can achieve a really fast serve.
As for the boxing, I have managed to achieve pro status. I have found that dodging left and right continuously throughout the match helps alot. This is because when your opponent throws a punch and misses he leaves himself wideopen so you can get in a big punch. You have to react quickly in order to achieve this. When your opponent misses you get a sort of slow motion feeling on the screen and this is the time to get in a good punch. Also note that when your opponents bar power is low it is always better to hit a big punch to knock him down instead of just compromising with jabs just to finish his power.
Hope these tips work 4 u as they do for me!!!!!!!!
