The "SHOOT FOR THE STARS" thing on the Blueprint map is just referring to the Sniper Rifle you can get there. Where it is located you can see Vinewood hills (Beverley Hills) where the 'stars' are.
Same for "TAKE CONTROL" It is just telling you to go to the control tower (which is in the square marked on the map in the base) to get the mini-gun
I don't believe anything on the blueprint map has relevance to the Mural
