I should have included the final form that did what I wanted:

find /media/richard/pre-fail/home/richard \( \( -type d -name '.*' 
-prune \) -o  \( -type d -name Downloads  -prune \) -o  \( -type d -name 
seamonkey  -prune \)   -o  \( -type d -name websites  -prune \)   \) -o 
-atime -42 -print

It wasn't until I got the "-type d -name '.*' -prune" phrase correct 
that I realized how much other "noise" was in the original output ;/

A tutorial question for fellow neophytes:
What 2 things had been flagged as possible problem sources early on?
