yeah that sort of thing

AFAIK you can run multiple copies from one folder without any problems.... worked for me.

in the profile theres an option for auto set gx resolution which changes the setting for WoW in the config.wtf prior to launch, but WoW only has a few settings on its video settings dialog, I don't know whats going on in WoW, my program does what it can and i should think it loads with obscure resolutions but just resets when you open the dialog.
