Yes. You will find an explanation in our Learning Manual: 
<http://lilypond.org/doc/v2.18/Documentation/learning/visibility-and-color-of-objects> 
– by the way: this manual is a ‘must-read’. It takes some time to work 
through, but it gives a very good introduction into basic concepts and 
it shows how to read the other manuals.
This will give you
omitRests = \omit Rest
:-)
So, no need for an abbreviation…

As Klaus already explained, the dot issue isn’t just as simple. You 
might try:
\layout {
  \context {
    \Staff
    \remove "Dot_column_engraver"
  }
  \context {
    \Voice
    \consists "Dot_column_engraver"
  }
}

This will move the Dot_column_engraver from Staff to Voice level and 
might fix the problem.
