Interior door panel installation

Help please :) Hey gang. I ordered two 72 door panels for my sons 71 dart. They didnt offer 71 panels so I ordered 72 and they said they'd fit. Questions are:

1. They didnt come cut or punched out for the holes for the door handle, arm rest etc... The holes are "perforated" so how do I cut them out without damaging the material/pattern/vinyl? What tools do you use etc...

2. Unfortunately, (and I never thought to inquire about), but the "clips" that secure the panel to the holes in the door are not attached/mounted. Do I need to buy a set of clips or can I use the ones on the "original/damaged" door panels I'll be replaceing with these new ones?

Any detailed instructions and adviced would be greatly appreciated, thank you!
