Basics for jumping??

I want to start my mare jumping. She's done LOTS of groundwork, she can turn on the haunches/forehand, sidepass, w/t/c, she's got simple lead changes down and is starting to get the hang of flying lead changed. What are other things she need to know? I ride western mostly and would like to do somethig different, I have someone who knows what to do to help me but she is out of town at the moment and I would like to keep her going well. Any suggestions would help thanks
