Yes, sometimes you do. If you decide to play a match, someone has to serve. Serving is really easy though. Your teacher will show you how to serve if you don't know how, or if you are scared.
For a basic tennis lesson, you want to instruct in how to hold the racket, possibly a western grip. Then you will wan to have a lesson about getting comfortable with hitting the tennis ball. You can have the ball hit higher so it is easier to hit.
Almost all of your joints are used in tennis, but the main ones in a tennis serve are the knee joints, and elbow joints.
You can hit an underhand serve in tennis; however, the overhand serve is more effective because it is more powerful. That is why you don't see the underhand serve used much.
