The redbook specification uses stereo, 16bit, 44.1khz wav files for storing the audio data. Other specifications have to do with track indexing and so on. As long as your audio is stereo, 16bit, 44.1khz, you're fine.
All manufactured CD-DA's are within redbook spec, yeah. Basically, redbook is just a specification to make sure cd players and the actual cd's can play together nicely.
