  As Brian says, it's a big subject.  You may find some material
of interest at the web page for a course I teach, on Extragalactic
Astronomy.  The main course WWW page 

       http://spiff.rit.edu/classes/phys240/phys240.html

  If you scroll down to the middle of the list of lectures, you'll
see links to a set on the methods astronomers use to measure greater
and greater distances:

                 The Cosmological Distance Ladder

          Step I: The Size of the Earth and Solar System
          Step II: The distances to nearby stars via parallax
          Step III: Using the color-magnitude diagram
          Step IV: Cepheids and the distance to the LMC
          Step V: Using Cepheids to measure distances to nearby galaxies
          Step VI: Estimating distances to distant galaxies

  Please feel free to use whatever appears appropriate.
