Does a guide exist for nero's mp3PRO encoder?
I want to know the best possible settings to choose to get the best possible sound quality with the smallest possible file size!

As far as I know not.

Maybe you should take a look at the preliminary results of http://www.soundexpert.info and at the postings of Serge Smirnoff here and at http://www.mp3pro.com where he also mentioned a problem with the Nero plugin, as far as I remember.
In short, 96 kbps (either CBR or VBR) seems to be the best compromize for mp3PRO between file size, quality and the sound coloration of SBR at higher bitrates. For which purpose do you want to use mp3PRO files, on a hardware portable, DVD player or your PC?

I managed to get 50 cds (speech) onto 1 cd using ogg-q1. The quality was very good! but obviously not perfect. I want to try it out with mp3PRO to see if the quality is better
If it's speech, I suggest you also try Speex.

I have tried speex also. I think I should try mp3PRO and compare the output...

AFAIK there are no switches available Nero's mp3 encoder.

I see, so hardware compatibility doesn't matter that much. Like Roberto wrote, there are special speech codecs that can go even lower than e.g. the standard 64 kbps mp3PRO bitrate. The actual MPEG-4 solutions for these purposes are TwinVQ that has been developed for mixed content (speech and music) and CELP (for speech only).
But if you can wait a few weeks, Nero will probably come out with an AAC+ codec that should sound better than all of these at ~16-20 kbps per channel. By the way, I'm not sure if the Nero mp3PRO plugin allows mono encodings, but if it does, it might also sound good enough for your speech material at ~32 kbps.
And you should also try WMA9 with its new "Voice" mode that is supposed to be competitive at these low bitrates.

I don't think so. MP3pro uses intensity stereo. For that reason, if you're using 64 for stereo, 56 (maybe 48) would make more sense for mono...

Is WMA9 still using ACELP.net for voice?

Don't know, maybe the EBU Technical Review will tell you something about it.
