1. Would it matter if the program i.e. superdump, usb loader gx, etc was loaded through hbc or not?
2. Would it matter what cIOS I used to dump the game... I think cIOS waninkoko r17 of IOS 58 is the best as it has usb 2 support?
3. What is the fastest program to use?
2. In Modern loaders and with newer ciOS no. Waninkoko r17 is very outdated. Use cIOS d2x v7.
3. Your USB Loader would be the fastest way (USB Loader GX, CFG or WiiFlow). It'll take 30-45 minutes and rips the game straight from the disc onto your hard drive; done.
It's the fastest you're going to get.
