Trivia: Actress Paget Brewster appears in this episode as an IT lady named "Debra Chambers." Brewster was eventually cast as a different character during season six named "Frankie Dart." In one season six episode, the character Dart mentions being unable to get ahold of the school's IT worker- a very subtle joke in reference to the character she played a year prior.

Question: Is Jeff still teaching at Greendale after Annie and Abed leave? I assume he is, but they didn't specify if he was keeping his job. Also, who became vice dean? The original one was murdered.
Answer: The implication is that Jeff will still be teaching at Greendale after Annie and Abed leave. As for who became vice dean? It's never shown, since it's not really important to the series.
