I kinda suck at bunny hops, actually.
For waltzes, now anybody please correct me if I'm wrong, but I see them as 2 footed 3 turns if that makes sense. You go into it off your LFO, and then land on your RBO. Basically a waltz jump is the first half of a LFO 3 turn, and the second half of a RFI 3 turn. So if you're proficient at those turns, and checking them, then a waltz shouldn't be too hard. What I'd recommend is, try just transitioning from those edges, and then once you get used to transitioning from edge to edge you can add the air and make it an actual jump, but for now treat it just like a step. You can add the power, and the jump that comes with it later, for now just think of transitioning from those edges.
That's just my recommendation, I don't have a real "coach" (though I do have a very knowledgeable guy I get advice from) and I've never taken lessons and I'm all self taught, so take that for what you want. I find skating is all about edge control.
