Christopher, I'm sorry it's too late, but I haven't receive any messages from postgres mailing lists for a month (don't know why). Just found your message in archives.
GiST is a great thing, it's generalised search tree invented by Hellerstein in 1995. It allows you to define custom data type, index access to them and custom queries. I have a little intro about GiST (not finished yest) http://www.sai.msu.su/~megera/postgres/gist/doc/intro.html Also, at the bottom of http://www.sai.msu.su/~megera/postgres/gist/ there are several seminal papers for reading.
