A mix of smaller eagle creek packing cubes and sacs I picked up on closeout. Magellans, Ebags, and a few other places carry similar stuff. I've gotten tired of trying to repack the bag I take on the next flight and especially when the TSA wants to see my camera buried in a pocket at the bottom of my bag.
The eagle creek "pack-it sac" has a plastic lining so it's not always easy to pack, but at least it doesn't slide around inside.
I don't have much smaller stuff, but for those coin purses can work well (something like this

All cords get cable ties (

Also I take shorter cords (monoprice has 1' usb cables) and tried to standardize on usb.
