The leaps themselves are much easier if you don't think of them as leaps at all, just chords in different places. That may sound odd, but in my experience it can make a world of difference. As an interim stage, make the leap from the top of the bottom chord to the bottom of the top one. Practice slowly so that you can 100% nail them every time - every inaccurate one is a set back, so don't be afraid to rweally slow it down. Only once you are completely sure of them at that speed, then step it up a notch (JUST a notch). Repeat until you are at about 120% of the speed you ultimately want to play it all the while keeping that level of accuracy. After that they're easy.
Lastly, what edition do you all think has the best fingering for this piece?
From the questions you are asking, it appears yo may well not be ready to play this. So the answer to your "how do I...." question is to learn some other pieces that give you the proper foundations to tackle those elements here.
