Yes, in total numbers Germany is the second largest donor of military aid to Ukraine after the US. In terms of fraction of GDP, there are other nations who have donated more, Poland, Bulgaria and the Baltic republics stand out here.
GDP based statistics of course favor smaller countries more but Germany is almost providing half as much as the US in total now and the EU combined almost twice as much as the US. I like to shit on my country too but those are some pretty clear cut numbers.
They were almost certainly referring to the winter & electricity gear. Unless there's something undisclosed, but I don't see that given that Ukraine still lacks a launch platform for Taurus.
They managed to adapt the Su-24 for Storm Shadow, no reason it couldn't be done for Taurus; they are of similar size and weight.
I think the compromise was that they need to be programmed on the ground, as the aircraft avionics don't offer a compatible complex interface, but a launch signal can be rigged. Since Both will probably be used against fixed targets (airfields, bridges, ...) that is not a big drawback. Still, it needs to be done, and is not quite trivial.
Is that a lot? That doesn't seem like a lot. I'm an American, our government's insanity gives us a false sense of what constitutes "a lot" in a military context.
I wouldn't say that it's a massive package, but it's part of a steady stream support. However as you say, it is hard rival the US military complex in size.
As someone already mentioned the Iris-T SLM system and radars are probably the highlight. Air defense is always needed and this is a modern system. Ukraine already got 2 of them before and presumably this is a newly produced one. So in this regard we really are limited by supply.
Iris-T is a state of the art medium range air defense system, reportedly with a hit rate in the upper ninety percentages. The Vector drones are also a couple hundred thousand per drone.
