I like this one for creating & managing content. They have some expensive software, but also a stripped down Internet version for $99 or so:

One advice I would like to share about doing audio for the web is to get a good microphone. Many people try to "get by" with a $15 cheapie from OfficeMax. There are some great pro mics available for $100 to $200 (now USB's too) that will give you a terrific quality of sound.
Also, if you are going to be doing lots of interviews over the phone, consider getting the Broadcast Host
http://www.jkaudio.com./broadcast-host.htm. JK Audio has all kinds of nifty tools for pro radio work. Broadcast Host is somewhat expensive at around $500, but it is the one piece of pro broadcasting equipment that truly gives you "control" over both sides of the interview, and makes you sound like an NPR broadcast. Another similar tool is from Telos, for about $500. JK Audio also has "Innkeeper," with a little more functionality than Broadcast Host.
Hope this helps.
PS. I visited your "singing cowboy" church site, and really enjoyed all of the audio/songs there. Nice job. All the best with your Podcasting!
