That's explainableI can't respond to that fully tonight, but regarding these points at least:
Those are two different types of attacks. He couldn't cut Daz Bones with an air slash, but he sliced through him personally at close range with a direct slash.
It's possible that Garp just wasn't using Haki to defend himself from Luffy, whereas he'd normally have some level of Haki active in fights. That's the only way he could be "suppressing" his durability.
