Just say \stemdown, then all the following notes of that voice
will have the stems pointing downwards, reset with \stemboth. 
(\stemdown, \stemboth and \stemup are actually shorthands for
property setting commands, see the file property.ly).

You probably used something like \translator{BarNumberingStaffContext} or 
\translator{OrchestralPartStaffContext}. 
Try \translator{ScoreWithNumbers} or \translator{OrchestralScoreContext}
instead.

If you try the latest development version, you will find a 
more competent program with a significantly improved manual.
As one example, Lilypond now has bar numbering turned on at the 
score level by default. 
You could also wait for the next "stable" release 1.4.0 which should
appear very soon.
