There isn't really such a thing as "too much"... healthy fats don't suddenly become detrimental when you cross over some arbitrary threshold of 100g or something like that. Natural fat is a perfectly healthy and viable source of sustenance. So are carbohydrates, too. Neither are inherently superior to the other, and how much of each is optimal to consume really depends on your personal context. Some people have had amazing results going low carb for a while. Some people, like me, find that upping my carbohydrate intake considerably has improved my well being dramatically. The only reason fat would ever become "too much" is if you're just eating too many calories and you want to lose weight. 30g of fat a day, sometimes, is perfectly fine. There's nothing wrong with moderating fat intake somewhat.
Just starting out, I'd say focus on the fundamentals. Eat primal approved foods and don't worry too much about macros... just eyeball a plate and have a a nice portion of protein, vegetables, and a carbohydrate if you wish. I'd recommend eating more carbohydrates and primal approved starch on workout days, assuming you don't have major health or blood sugar issues. GO for the 80/20 approach and tinker the specifics when you decide to take on a more specific end goal.
I've been diddling in the PB for 3 years now, and I've finally pulled the trigger and eliminated gluten containing grains entirely from my diet and I've noticed a big difference in just 3 weeks. No more hating my life taking a dump, ect. I'd really recommend giving that a try. Some people, honestly, do perfectly fine eating cereal grains and dairy, though. I thought I was one of them for a long time, but I might not be.
