Double kettlebell work is incredibly awkward at first. The rack position is tough because you can't find your hip as easily.
People who have the 'bosu' thing going on tend to do better finding a good position.. In KB comps you used to see people use their belt to aid the rack. Now I think it's illegal.
I'd suggest spending time in the rack and only the rack each session. You'll develop a great tolerance to lactic acid.
You'll get used to the clean with a wide stance. Over time you'll adjust your swing and that'll be the least of your problems.
And if you don't think kettleball squat cleans are difficult, I say, step up to the med-ball
