After doing some digging through a few books, I found out some info about the Jumo 004B engine. It took between 12 and 15 seconds for it to respond to a throttle change. If the pilot pushed the power forward too quickly the engine either conked out or (more often) erupted in flames. Due to the lack of high-temp metals the engines were only good for 5 hours of flight time. After that they had to be changed. Later models increased the engine change time to 15 hours. By contrast, a DC-10 can use the same engines for about 20,000 hours.
BMW 003 D jets produced more power (2,425 lbs vs. 1,980 lbs) and were a LOT less tempermental. You could rapidly change power settings and it wouldn't complain much.
As for why the Luftwaffe never had more than 200 operational Me 262's, that's easy. Nearly all 262's were transported by rail and not flown to their new homes. Since Allied aircraft found trains really fun things to shoot up, hardly any got to front line units. As the book Warbirds Tech Series Vol 6 states "In one instance, a local Autobahn was used as a test field before the airframes were packed up and sent by rail to their parent units".
Finding info about the Arado isn't easy, but Pyro mentioned the Wings episode about it.

I'm gonna go out there and remove one of His creations from this universe.
And when I get back I'm gonna drink a bottle of Scotch like it was Chiggy von
Richthofen's blood and celebrate his death."
