I used a butter knife to gently pry out the plugs. They were in there pretty tight, but they'll come out and no, I didn't damage them at all. I was more worried about marring the interior panel around the plug, so I used some painters tape around the hole so the butter knife would not mar the panel.
For each plug, start on one side and when that side of the plug starts to come out, then do the same for the other side of the plug, pulling it out evenly until you have it out enough that you can use your fingers to pull it out the rest of the way...
