need tips on jumping wake

I am a beginner wakeboarder, and I have down riding and crossing the wakes but I am ready to jump the wake from heelside, but that is presenting me a huge problem because I seem to skip alot over the wake, and I am not sure on how far I need to go out before I cut in for the wake. How should I be standing when I hit the wake? I crouch down a lot, but I don't think thats the way to go when jumping from what I have seen, do I need to pull my legs up when I am in the air or will that just make the landing harder? As you can tell I really want to do this and do it right, and any advice shared would be a great deal of help to me, thanks.
