First things first, read the jungleflasher.pdf file, it is VERY IMPORTANT, anyways if you have to have a via 6421(usb models available) or equivalent its a good start, and you'll need a powersupply made for x360 dvd-rom. Do Not use the x360 to power the drive.
That Said, for your lite-on 360 you'll need an extra(possibly two chips) chip to read the dvdkey. MRA hack(for updated 360's) & ck3-pro(connectivity kit 3) chip & Jungleflasher
For the BenQ all you need is the powersupply and Jungleflasher
As For powering the drive the ck3-pro does that too, or you can get a standalone powersupply, you cant use your pc itself

I have found Team-Xecuter to be very helpful. They are actually the ones that make the tools you will need to flash your drive. They also have some good tutorials to support their products. For my Lite-on 74850c I used this guide to flash it. And also read through the jungleflasher tutorial. You should be able to find everything you will need there, even links to sites where to buy your connectivity kit.
