Well, you've got too much going on and sometimes it's just best to "chalk it up to experience."
I agree with the other posters here though. The bearing is inside the hub and is essentially protected from all the outside elements and impacts. Where would they put those stickers? I'm sure they probably get damaged during the removal process but short of that how else would they get damaged except for some really big impact, at high speed, on the street. Hopefully you are good for a long time now.
