Not only that, but when NASA runs out of SMEs for the SLS rocket, they will have to come up with a new engine at huge expense, put it through a testing regime, and more or less redesign the rest of the rocket as a whole new vehicle anyway.
Not quite. Once the stock of RS-25D engines left over from the space shuttle program are used up, they'll be replaced by RS-25Es, a cheaper one-time-use version of the space shuttle main engine. They may need to produce two more sets of the 25Ds before the E's are ready, though. They're reusing the old shuttle engines on a disposable rocket for two reasons: they're already a man-rated design, and the engines themselves are already paid for.
Interesting note, Discovery's engines, at least, may make it to museum some day; looks like they're being earmarked for ground test structures, rather than flight.

...astronauts wearing an ACES, Sokol or some private sector pressure suit...
I sort of hope they use Sokol suits, or something with compatible valves, making it easier for astronauts to go up in one type of space craft and, if necessary, return in a different one. Of course, the seat liners would also have to be compatible with the ones used in Soyuz, but it'd be nice to be able to switch crafts without having to send up a second pressure suite and seat liner, like we did when we had astronauts switching between the shuttle and a Soyuz mid flight.

The main engines and associated plumbing were removed at NASA's behest, not the museums. NASA plans on reusing the them (and, unfortunately, disposing of them) on the first three flights of the new SLS rocket.
I believe they removed most of the tanks and plumbing from the RCS and OMS systems because the fuel they use is particularly nasty (they have to wear heavy-duty hazmat suits when working on them), and they were worried that the equipment would still be contaminated, even after it was purged, and most museums don't toxic self-igniting chemicals in their exhibit halls anyway, so it was safer just to completely remove all the interior components. It's not like they'd be on display anyway, unless you went crawling around in the interior, or the museum did a cut away (which, in this case, just makes me shudder).

But I thought there were no beginnings or endings to the Wheel of Time?
Sanderson's been doing a wonderful job; his stuff has probalby been the best we've seen since book five or six. (Yes, there were cool bits here in there in 7-12, but they're diamonds in a whole lot of rough.) I'm sort of sad we don't get a few more Sanderson books.

The title of this story is misleading. It isn't the rockets that are grounded, its the spacecraft that sits on top of them.
Also, for what it's worth, the shuttle wouldn't have been help matters much if the Russian's can't fly a Soyuz. While the shuttle is fine for swapping crews (in fact, the shuttle's runway landings are gentler than the Soyuz's parachute landings, a good thing for people who have spent the last six months in 0g), the shuttle can only fly a two week mission, meaning without a Soyuz attached to the station, we'd have to leave people in orbit without an immediate way home, a risk that neither NASA nor Roscomos is willing to take. The Soyuz itself is only rated for six months in orbit, giving them a limited window to fix the problems before we have to talk about unmanning the station.
