That's a good summary of what to do with two parts.  When there are
three on a staff, and the rest belongs to the center part, sometimes the
rest will collide with either the descender or ascender.  In such a
case, the rule is that the rest must *precede* the stem regardless of
the stem's direction.  You can't let it be tucked in under a note head
after a descender.  I have whole pages of music where almost every
measure is noted this way, from 1810 or so.  The only place I have seen
this rule written out was on the Denemo website IIRC, but they must have
seen it somewhere.  I would be nervous about scanning the example
because the "author"(!) claims copyright.  daveA
