(1) The "ngb_____.pfm" form of naming is a holdover from the days of MS/DOS eight-dot-three naming conventions. These names have been retained for backwards compatibility with MS/DOS and Windows 3.x (yes, there are still users of MS/DOS and Windows 3.x). The actual font names are in the .pfm and .pfb files. The names used by Windows are specifically in the .pfm file. 

(2) The .pfb file is the Type 1 font itself. The .pfm file containing naming and other "font metrics" information (including pair kerning information) not otherwise available in the .pfb file. Windows needs BOTH of these files in order to use the font. The only alternative is that ATM can install a Type 1 font IF you have the .pfb file and instead of the .pfm file, you have the corresponding .inf and .afm files from which ATM can generate a .pfm file! If all you have is the .pfb file, you are pretty much "up the creek without a paddle". If you don't have the .pfb file, you don't even really have the font. 

Unless you need to support Multiple Master Type 1 fonts, you don't "need" ATM to display and print using Type 1 fonts.
