alutLoadWAVFile will give you a pointer to the raw data in PCM format -- 
the header information isn't there (it's reflected in the format 
information).

I think you've interpreted things correctly -- here's  a rewording:

- 8-bit mono would be unsigned bytes, and you would step one byte at a 
time through the data
- 8-bit stereo would be unsigned bytes, and you would step two byes at a 
time, with each pair representing the left and then the right sample
- 16-bit mono would be signed 16-bit words, and you would step one word 
at a time through the data
- 16-bit stereo would be signed 16-bit words, and you would step two 
words at a time through the data (left sample then right)
