As I recall, foobar2000 comes with some presets for various common encoders, including lame.exe. Just click the menu Foobar2000 > Preferences, then choose Diskwriter from the list on the side. In the middle of the preferences window should be a drop-down list called "Output Presets." I recommend "LAME --alt-preset standard." Once you've selected it, click the "Edit" button right underneath, and all you have to do is specify the path to the encoder (lame.exe). I recommend using LAME 3.90.3 or 3.96.1 (both are well-tested versions).
