NSL wasn't the first episode that showed where Lynn Sr. worked before the resturaunt, that honor goes to "A Novel Idea". As for Lily pronouncing Lincoln's name, we don't know for sure if that's the first time she  pronounced Lincoln's name, she could've been able to pronounce it off screen prior. She was also able to pronounce "These guys!" in "Changing the Baby" which was back in Season 1. Even then, I don't think it's strong enough to be considered a reference to the episode, because I don't think it matters that much.
