You actually don't need all but like 2 or 3 of the vaccum hoses hooked up if you don't care about smog testing. Dont ask me which ones though since my buddy capped off all those not neccessary on my '85 I had when we did a motor swap. If your front radiator support hasn't been swapped, you should have a diagram of how the hoses go right on the radiator support to the left of the hood latch. I have an 83 K10 with the diagram there and it is also on the 86 K5 I just picked up. If you don't, I can try snapping a pict of my diagram and see if it gives enough detail for you to figure it out. By the way, my 83 originally had the exact setup as you listed for yours so the diagram should be exact.
