Searching on YouTube will likely give you a lot of the stuff you're looking for.
There's a couple main things to remember.
1. Quick feet are happy feet.
2. If you are losing a juggle at all, let it go, don't try hard to save it. That's how injuries happen. Make sure you are on a surface where you have no hesitation in letting the KB fall to the ground at full speed if anything goes awry.
I have the H2H video, I never really got into juggling, if you decide you want it PM me and we can work something out.
