Is there a gambit function that can duplicate an arbitrary scheme object available or do I have to write my own for each of my data structures?

You will have to specify precisely what kind of duplication you want, which amounts to a definition for each of your data structures. See http://www.nhplace.com/kent/PS/EQUAL.html for a good discussion of this issue.
