Question about Cubase Pro 10 download assistant

I bought Pro 10 a few days ago and just downloaded the 21gb image and the .15 update. I was just looking through the other icons on the assistant.

Am I also supposed to download stuff like the separate Halionsonic Se, marimba, Vst Connect Performer etc? Not sure which of all these are already part of the 21gb image. I’m not installing anything till next week when a new 2tb 970 evo arrives.
