The white things are self adhesive cable holders/clips. I got mine from one of my automotive parts suppliers, but you might find something similar at radio shack. Or you could use instant gasket to glue the wires in a few spots to keep them from moving around, not as pretty, but cheaper.
The plastic bender is basically just a long wire/filament that heats up, and a arm to bend the plastic over. It heats the plastic until it is soft and then you bend it. Might get the same results with a heat gun, a vice and a piece of wood to bend the hot plastic. Practice on some scraps first to get the technique.
