Jordan and Danny named their daughter Rebecca Tripp after Jordan's grandmother.
The light that Danny turned off at the end of his final scene is commonly called a "ghost light". When there is no work going on in the theater, commonly after everyone has left for the night, the ghost light is lit for both safety and superstitious reasons. Traditionally, the only occasion the ghost light would be turned off when leaving the theater would be when the theater is closing for the final time. Danny turning off the light is, most likely, an acknowledgment from writer/creator Aaron Sorkin that the series has come to an end.
Goof: When the doctor strips off the bloody smock he still has a spot of blood on his right shoulder. When the camera cuts back to him after cutting to Danny the spot is gone.

The lawsuit being filed against "Studio 60" is nearly identical to a lawsuit filed against the writers of "Friends" (of which Matthew Perry was a star) in 1999. Some of the allegations in the lawsuit that Matt reads out are identical to allegations made in the "Friends" lawsuit, including sexual discussions about the lead actresses and a discussion about possible eating disorders.
When Danny and Matt talk about why Harriet isn't back yet from the film set, the clock in Matthew's office is wrong. Instead of 1 day, 20 hours and 29 minutes it shows 0 days, 20 hours and 29 minutes left until the show.
When filming the Russian roulette scene of Harriett's film, in the scene of the 2nd take the 'blood bag' is clearly not there. Yet, when the actor pulls the trigger blood goes everywhere, and when he sits up a 'blood bag' is strapped to his head.
