Next thing is to start out simple. Don't go out and buy a pattern that seems more than you can handle. The first thing that I would try to make is a bag, pillow case, or simple skirt. They make patterns for beginners (click the links). So, when you are at the fabric or craft store pick one up. After you get the pattern ask someone at the store to help you find what you need to make that particular item. They can help you find everything, all the way down to the thread.
If you are still not comfortable with attempting this new adventure, find someone who sews and ask them to join you. Sewing is fun and can be a great way to spend quality time with your friends.
Another thing that will really help you along is to practice sewing straight lines. You can use scrap fabric or an old piece of clothing. What you will want to do first is find a focal point on your machine.
Hope that helps you start out on your sewing adventure. It is sew rewarding to create things on a sewing machine, I promise it's worth practicing. The more things you sew the easier it will be to make things you really love. Happy sewing!!
