You are reading an old version of the man page, not the one of the
that came with the last version of MPlayer you are using (r24859).

The reason may be that before the man page was installed in 
/usr/local/man/man1
and now it is installed in
/usr/local/share/man/man1

May be an old one is still in /usr/local/man/man1 and it is showed
before the one in /usr/local/share/man/man1

Wrong, libmp3lame IS a valid lavcopts option (at least
since 1.0rc2 is out, I don't remember when it was changed in libavcodec)
also the correct way to use lame with -oac is -oac mp3lame.

Are you really using a recent version of mplayer? (r24859)
Does configure find lame? (Checking for libmp3lame (for mencoder) ... yes)

No.

If you want to encode to mp2 yes, if you want to encode to mp3 no.
