I'm glad to see Jay's still around here from time to time. Good to see you post my friend.
The 80% diet rule is a good and accurate one. Kinda Paretto's Principle with that whole 80/20 thing.
A couple points I'd add:
Don't fear carbs. They do a few good things and are not completely and utterly evil. I would keep them primarily "Paleo" though in terms of tolerance. LImit sugar, keep starches to yams, sweet potatoes, carrots and other roots and tubers. Fruit is harder to overdo than most think, but can be done. Keep things to water heavy choices like berries, oranges, apples etc and you should be fine.
I'd honestly set macros on grams/lb instead of percentages.
And if you don't think kettleball squat cleans are difficult, I say, step up to the med-ball
