Hmm. The 8-byte encoding definitely sounds like S3TC or something very similar. As for the other, I'm not sure, good luck =)
(Edit: I was going to mention this but forgot: in case you were unaware, the extension for these textures is '.tpc' if you want to generate them for your override directory - there might be problems with running out of texture memory if you try using a bunch of TGA textures. Also, at least part of the data after the pixel data (the text part) appears to be the same format as the .txi (texture information) resource type, so you might want to keep that around somewhere as well)
