Knee pads are not needed, guys cant last more than a minute in her lips. She uses a different lube, and ice is not needed either, I have watched her take some huge guys.
Make sure you get your daughter a comfy pair of knee pads. They will come in handy servicing BBC. Also it might be smart to buy her a case of KY lube to bring to college. That and some ice packs for when she's swollen from a night of rough sex with a BBC.
