Taylor's comment that Stars Hollow "would have him to kick around again" is a reference to Nixon's bitter comment to the press following his loss in the 1962 California gubernatorial election.
When Lorelai, Sookie, and Michel were giving the speech about the Dragonfly at the town meeting that Taylor required, he asked if 18 parking spaces was going to be enough and Lorelai said it would. Now Lorelai is requesting two more parking spaces.
At the end of the episode, when Lorelai goes upstairs to Luke's apartment, to the left of the door you can see a wall curio containing wooden numbers and letters. This looks to be the same one from Dean and Lindsay's apartment, hung just below the counter behind the dining table, in the previous episode.
