One problem. Revelation was written significantly after the fall of Jerusalem. Other than that you are right on.
The book of the apocalypse was written during the AD 60s
1. external evidence: the Syriac version of the book of Revelation begins by stating that it was “written in Patmos, to which John was sent by nero Caesar”. Also the Syriac work “the history of john, the son of Zebedee” states that nero exiled John.
2. internal evidence: Rev 1:9, 2:10, 12:11, 13:15 states that it was written in a time of persecution. Rev 17:9-10 talks of 7 ‘kings’ - the 6th of whom was reigning and the 7th who will reign a short time - note “will reign”. this is nero, the “6th Julio-Claudian emperor” and the 7th was Galba who reigned a few months
3. historical evidence: there was no widespread imperial persecution under Domitian in the 90s.
We don't know that, actually. It's based on one line from Irenaeus which is ambiguous. It could mean that John wrote Revelation around AD 90. It could also mean that John -- the John who wrote Revelation -- was still living in AD 90.
Revelation makes a lot more sense if you view it in a partial-preterist framework, as a lot of scholars both Catholic and Protestant have taught.
