The Brake Booster Vac line on my silvertop runs from both ends of the Throttle body assy. One of the vac lines runs from it near No4 as shown on your diagram and the other from the point shown on the extreme right of your diagram (ie near No1 TB). They then join together in a T before going to the brake booster.
The hose from the rocker cover goes to the air intake main hose (between the AFM and the plenum). If you have the standard hose, there should be a moulded-in metal tube exiting the front side of this hose.
The ISVC valve line that you marked "?" goes to a large metal pipe coming out of the bottom/front of the metal plenum.
The small vac line coming out of no4 TB snakes down and disappears under the plenum area with all the other vac lines (unfortunately I can't easily see what it connects to with the plenum in place and all the other bits and pieces in the view).
As for the other three lines, its very hard to see where they go from-to without removing my plenum and other bits and pieces. Hopefully someone else can help you out with those.
