See here for LAME: http://audacityteam.org/help/faq?s=install&i=lame-mp3

and here for FFMpeg: http://manual.audacityteam.org/index.php?title=FAQ:Installation_and_Plug-Ins#installffmpeg

These should be used with Audacity 1.3.12. If your version of Audacity is older than 1.3.12 I would recommend that you upgrade to 1.3.12 first.
You can get Audacity 1.3.12 from here: http://audacityteam.org/download/
