Most jacks will have a rubber pad which should be enough to protect things. If you dont have that you could find a scrap of rubber, wood or something soft though I wouldnt worry about that if you are infact using the jacking points (and not the pinch weld/jack stand points). You will need a low profile jack as the car is pretty low and the jack points are fairly far inwards.

Front jack point is in the middle of the front crossmember, theres an arrow pointing towards it on the plastic undertray.
The rear jack point is the diff.

Jack stand points are in the typical spots under the sills on all 4 corners.

A hockey puck with a slot in it is frequently used when jacking from a pinch weld/jack stand point to keep it from just folding over. You can protect it by never doing this if its not absolutely necessary. These arent intended to be jack points instead they are where the jack stands would go (an actual car lift would be different as its lift all 4 points at once). Always jack/lift from the jacking points and avoid jacking/lifting from the pinch weld/jack stand points.
