Was just building my own list like this for all the models. Glad I found yours before going all the way!
You can find the details to some of the mystery files by attempting to open them as containers.
0001.PC can be opened as a container.
-Within are .BCH files and .CGFX files.
-CGFX open as textures of different effects (burn, sleep, etc) but I'm not sure.
-The first .BCH file is the same as the 0002.BCH file which opens a blank in Model, but has the Star.png texture in the Texture tab.
-The other .BCH files are 3d Planes whom the CGFX textures are probably slapped on in the game. They come with DummyTextures if you check their Texture tabs.
-0002.BCH is explained above
