I'm not quite sure what you're asking, but:

Pass 1, 2, 3 doesn't make any sense.  You'll be wasting time on
pass 2, and getting no-better results with pass 3 after pass 2.

Pass 1, 3, 3 is the only way that makes sense, and should give better
quality.

You don't need "=yes" after each option.

Something along the lines of "nr=600" in your lavcopts should help
greatly.

If you could upload a short sample to MPlayer/incoming (or anywhere
else), I'll take a look at it.
