Regular damage is 'resolved' before critical damage, or to put it another way, facedown damage is dealt before face-up damage. In your scenario without Greedo your opponent would draw three facedown cards and then draw a card face-up, for three hits and one critical hit, yeah? You wouldn't draw the face-up card first, then draw the three facedown cards, or draw two facedown cards and then the face-up, or any other combination (I would hope).

Greedo turns the first damage card for the round face-up. In your scenario the (for the sake of this example, extremely pedantic) opponent would draw his first damage card, place it facedown, then flip it face-up to resolve Greedo's effect, before drawing two more facedown damage cards, and then drawing the final card face-up to resolve the crit.

tl;dr: Greedo turns your first uncancelled damage into a crit, and the rolled crit is resolved as normal.
