I don't know anything about fxb files, but I'd certainly recommend Gmax + NWmax for general NWN modding. You'll probably be able to get quite good with Gmax before you miss any of the features that 3ds Max adds.
I've used Blender only when messing about with importing/exporting different formats, and absolutely hated the interface (though in fairness, I'm very efficient with gmax/max's alt + mouse viewport navigation and keyboard shortcuts, so anything as different as Blender was bound to feel awkward).
