Basically, just a ratchet and a push pin puller makes things easiest. You'll likely bust some of the clips taking them off, so go ahead and order new ones from the dealer. There are a total of 28 retaining clips on the front and rear, around 20 push pins and that's about it. It's easiest if you're replacing for the inner guards at the same time. If you're only doing the flares, you'll also need to replace the plastic rivets (seems like it was six per flare in the back and 10 per flare in the front). I'm not positive those are the exact numbers, but it's close.
