The sndfile-info program distributed as part of libsndfile does all
of those things.

for mp3 files you can use tools like mp3info and mp3info2 to read
information stored in the ID3 tags. 

midentify (part of mplayer/mencoder) prints not all but much of the
information you want, like bitrate, length, sample rate, channels, etc.
