What do they hope to learn from this new super-secret surveillance unit
This sounds more like CIA/NSA territory.
This sort of surveillance does sound more like what what you would expect out of the CIA -- which is hampered by federal laws limiting them to spying on international communications and foreign nationals -- or the NSA -- which has invested in a huge new facility after admitting that there's just not enough power to come close to breaking a significant amount of encrypted traffic. The big question is why the FBI would jump into something it's never been a major player in before.
Best guess: they're trying to update wiretapping. They've been getting increasingly alarmed and vocal about just how little wiretapping actually buys you now. If you really want to keep something secret, you can just use an https encrypted connection to any one of numerous services that keep no records and have no mechanisms for spying on their users.
They recently floated the idea of requiring backdoors be installed into such service, the way telecom hardware is legally required to support conventional wiretapping. that idea had no real support in technical or public circles. Even if you trust your government, it's much hard to game a system that requires someone to go to a location within the your country and physically connect to equipment owned and operated by a someone else than it is to find an exploit in a protocol that can be prodded by anyone online and which would have to be implement by everyone from Facebook to Club Penguin.
With no widespread support for spying-as-a-service, they're stuck traffic-tapping the hard way: inspect every packet for the start of an HTTPS handshake so you can break the connection, or somehow crack an encrypted stream with incomplete knowledge. They still have no idea how they would reliably accomplish either of these. However they do it, it will probably require new laws to make it feasible. It sounds like the program casts a wide net in an attempt to find something that works, and is trying to keep it quiet because they don't know what solution will rise to the top, or how knowledge gained about the process now could be used to defeat it technically or legally later.
