Sure :)

First, a few refs on graph theory in general:
The references there include a book from Springer in PDF form :)

The problem of is one representing graphs in RDBMSs is at the outer
edge of theory right now, so you'll be doing some pretty serious
coding to make it happen.  The kind of graph where the most has
already happened as far as RDBMSs go is a tree.

A lot of the general questions about graphs are essentially
mathematical in nature and end up with phrases like "NP-hard" or
