Unlike FSX, I found that the default jets (734, 773, etc) in FS9 have no blank/white textures- only repaints for the default airlines.  I would like to see if I can paint some of them, but I can't do it unless I have a blank texture to work with.  After doing a few searches involving certain keywords in the file library, I wasn't able to find any.  Does anyone know of any blank textures that I can paint on for these aircraft, and if so, where might I be able  to find them?

I'm no expert in these things but I think that the thing you should search for are the so called "Paint Kits".

Good luck

Nearly all the fsx default have white as one of the option planes (eg airbus 321 white), Also the SDK has 2 full paint kits for 737 and 747 If I recall correctly sdk\Environment Kit\Modeling SDK\SampleTextures
