Might leave the observatories for another trip. Not all rentals are allowed up there (or on Saddle Road, sadly).
Definitely a good idea to spend a night Hilo-side. As others have pointed out, it's a looong drive from Kona to Hilo.
I just got back. Didn't have time, but asked a very knowledgeable local friend about the green sand beach (he fishes out at South Point a lot). Don't remember the exact distance, I'm guessing a mile and a half, but definitely walkable. Since you've been to the islands before, you know to lock the car, don't leave valuables visible...
I just got back and your post is making me homesick to go back already!
At VP, you might check out Mauna Loa Road, if you get time. Paved road, about 11 miles, fantastic views.
