by the list you have shown here it seems as though you have a great start. maybe the reason nobody has chimed in is because most people that get this type of equipment already know how it goes together before they purchase it, or get exact specs from the retailer which they purchased. but simply install your exit exhaust near the top of the tent just below the light's level (at the highest setting if you have adjusting light hangers) then, your intake blower should be installed very low and on the opposite side of the tent that you installed the exhaust. The ducting just connects from one item to the other. if you can attach the duct to the cool tube (if it is one of those types) so that the heat is being immediately sucked out. there are directions arrows on the fans/blowers telling which direction they blow. exhaust (up high) blows out, and the lower (intake) blows into your tent. your fans are the same size so it should be pretty simple and you won't have too much going in and not enough going out or the opposite. I, honestly, am not familiar with the LED lighting, and to mbe honest i don't really know why you have it because the hps/mh is all you need, well, that and the correctly corresponding bulbs.
