<description><![CDATA[Description.]]></description>
<pubDate>Mon, 28 Feb 2011 16:01:17 -0800</pubDate>

I checked further into the specs and the absence of the hours isn't significant.
When subscribing, everything appears correctly. Your feed is lacking the 'itunes:subtitle' and 'itunes:summary' tags which should contain the descriptions and info: iTunes is managing to draw the information from the 'title' and 'description' tags in each episode.
However in the Store page, only episode 9 shows a duration and a description: I can't see any reason why this should be as the code isn't any different from the other episodes. Have you modified the feed coding recently (this seems doubtful for over 300 episodes) - the Store could just not have updated. Otherwise I can see no reason for this, though you might want to start using the itunes tags I mentioned. This page gives a basic sample feed so you can see what I'm talking about:
