i can only say for deep octa -
put all the wires in the pouches along the front (the capped ends go there), and put all the other ends in the springloaded "screws" that are in the center. Then I work with two opposite facing wires a time, i hold the lock-screws and push the wires by outer-edge of the hands down, so that the force is spread over bigger area than if you tried to move it by just the locks. Once i get the first two locked, i rotate the box and do another pair (90 degrees to the first one). Last 4 are usually quite easy. Also note it's hardest to set it up for first time, as the fabrics is slightly "rested" from the package. After few weeks and about 10 usages, it's actually very easy to set it up.
As for the hood - i'm using it with inner baffle as well, on deep octa the hood has to be attached to the wires before you lock the wires, so that adds complication to the process
My trick is to put the wires through the deep hood, then move the deep hood all the way down to center, so it gets less in a way, then i lock the wires, and then i move the hood back in place where it's supposed to be. For easier acces to the lamp (for gels..) i usually leave two wires unattached to the hood, and then just rotate the octabox so these two are down (so it's hold in right place by gravity).
I had been told to keep the octa disassembled for first few weeks, before the material gets more accommodated to the tension, but honestly i just did that twice, and now i store it just collapsed, but assembled in the case.
hope this helps
