What tools are there out there for determining why a site takes so long to load pages?
I'm using a very simple theme that I changed to fit my needs, it's a brand new site with only two test posts and it takes a while to load.
I used YSlow for Firebug and it gives the site a Grade A (90) so that doesn't really help. Is there anything else out there that might help me figure out what's going on?
try using a profiler like xdebug, how to setup:

according to your site, the page is taking a long time to generate and doing a fairly large # of queries:
<!-- 28 queries. 2.728 seconds. -->
<!-- Dynamic page generated in 1.553 seconds. -->
<!-- Cached page generated by WP-Super-Cache on 2010-01-12 16:23:03 -->
so.. was there a plugin that was recently added that may be doing a lot of db calls?
supercache will help a lot, requests won't need to run all those queries if the page is cached...
