What do you want to edit here?
Is that image a copyright?
Is that JPEG all you have?

You are asking for help performing the most basic tasks in Illustrator. Better you should learn the program. There are plenty of tutorials at Adobe.tv and on Youtube, as well as on Lynda.com. Or you can hire someone if learning Illustrator seems liek too big a task. It is a powerful, complicated program, and it could certainly use more intuitiveness. I feel it would be pointless to offer stap by stap instructions here.
