Oh, is there some sort of rule that they have to wait 90 days before telling us everything? I don't recall ever seeing that before, but I'll take your word for it.

No, that is just when LM submits the 90 day report to NASA on the flight with all the data.

During the EFT-1 launch, we all know the rocketcam captured video of the ascent until webcams from the Orion took over. But I ask this: how can we have visual evidence of the Launch Abort System jettison if we did not see the smoke go by the lens? It kind of gave me a hint that the jettison motor failed until the PAO gave the confirmation.

Visual evidence is not needed. They have telemetry to confirm that it jettisoned.

I think Mark Geyer said (in an interview just after launch) that there would be video of the LAS separation (from inside Orion), which I've been waiting for. Am I wrong about this? Regardless of it's real value, I'd just like to watch it.

Me too. I only saw the jettison motor fire during the first LAS Test in 2010 as well as the static firing of the same motor on a testbed.

The footage was briefly played in fairly low resolution during the press coverage of the event. The coverage has been uploaded to Youtube and the moment is here (2:45:42):

From what I saw, the LAS jettison was in slow-motion and played seven times in a row; the feed switched to Mission Control Room on the seventh playback.

Thanks okan170 for pointing that out. I guess i was hoping for something a bit more dramatic.

Well, considering that I've not seen any windows in the BPC, I'd wager that it'd be pretty dramatic if you were
inside the cockpit… launch notwithstanding!

Here's a post-flight summary of the EFT-1 mission & results presented to the NASA Advisory Council HEO Committee on January 13, 2015. I've extracted these relevant slides from a larger presentation by HEOMD.

At what speed can the windows stop objects? If there was a breach from the windows, what will the astronauts do? Also if there was damage to the CM or ESM, what will they do?

Speed is not the only relevant factor, mass of the object also matters.
Those are outer windows, there still are inner windows on the pressure vessel. if there is a breach in the pressure vessel, the crew will put on suits.
As for what the crew will do for other damage, depends on the damage. There is no simple way to answer the question.

I will just add that space is BIG. Really, really big. That trip down to the chemist's is nothing, compared to space.
In other words, there isn't all that much stuff flying around out there, per cubic meter, big enough and moving fast enough (relative to your vehicle) to cause serious issues. (By "out there" I mean beyond LEO.) There is an awful lot of space between the pieces of matter (dust specks, mostly) that are out there, as well.
There is more orbital debris in LEO, by a lot, than you will find natural dust grains flying around BLEO, that could hole your vehicle. Apollo window analysis showed that cislunar space, anyway, is pretty benign when it comes to potential impactors that could result in a Bad Day.
That said, there are somewhat well-known arcs of material, which cause the various meteor showers we see every year. The mass concentration is a little higher in those streams, which are mainly made up of comets that have disassembled themselves as they rounded the Sun. But even with those, we don't see significant issues with spacecraft in LEO, which are pelted by them several times a year. So, still, I don't think it's a problem that can't be overcome with a little common sense in design and in operations.
