This all is confusing please answer these questions:
What all is needed to make USB loader channels tell me every file needed?
Does call of duty modern warfare reflex work on usb loaders because it always gives me error 002 on gx?
Wil this work on a 4.1(Official) softmodded wii?
just get Loadstructor and you should be set (you'll need the common-key.bin as well). Loadstructor will make USB loader channel wads of games directly from your wbfs formatted hard drive. If you get 002 error, i'm pretty sure when making the channel you can just tick a box that says something along the lines of "fix error 002". After the wad file is outputted, simply install it with your favourite wad manager and boom, it will appear on your wii menu.
knowing you rockstar, that should be enough to get you through.
in summary
1 - loadstructure, wad manager
2 - should work if you set options to "fix error 002"
3 - should work on all firmwares
