Thanks for the links, I went off and made me some .ogg files with quality of 8 and 10 (don't like odd numbers, heh). With that in mind, I went to look up the Monkey's "loss less" compression and tried some files out. When I get back home today, I will go back and do some MP3s, with LAME at 320k. With ogg and mp3 at 320k, then monkey's, I'll get a good idea of what I want to recompress my audio to. With monkey, I know it will sound quite good, but I still want to save some space.
Even at the highest compression with monkey, the file sizes don't drop enough for me. I realize that monkey is trying to be the highest reproduction, but their sizes are still a bit too high for me. I'll go home, plug my headphones to the GXTP and compare a few tracks.
