The ReiserFS is just a warning, and it is normal. Everyone's empeg says this. Just ignore it.

The latter quote is actually three different things, only the last line of which is abnormal, and it pretty much explains itself. The VBR header on the MP3 file it's playing is invalid. You should fix it and reupload that track. I imagine that FFing and REWing within that track doesn't work too well as is. Also, I bet that it doesn't restart after power loss in the same place as it was when it shut down. Otherwise, it should still be fine.
