To answer your question about weights.

1. If the purpose of a study is analytic (hypothesis testing,
studying relations between variables) then Richard's student may not
be really interested in the original target population.  As an
example, she might never report the weighted counts; she would report
the sample counts for crucial variables. The only weights that I
would suggest, if any, are those which correct for non-response and
unequal probability of selection.
Thanks much for your detailed responses, Steven. She has a sample of adults and she is thinking about limiting her analysis to young adults ages 18-24. What you suggest sounds reasonable.
