Matt,
I'm a little confused about your exact goal. Metering is generally shown visually in real time, and I assume your mp3 stream is also real time, so I don't understand why you would be trying to work with offline rendering.
Assuming that you're converting the mp3 stream to audio as it arrives in real time, then you should be able to obtain level metering data from the Float32 audio stream that's being sent through CoreAudio.
Offline processing is for running through data faster than you can listen to it (or slower, if the processing is really heavy).
